See Anemone

Anemone hupehensis

Japanese anemone, Anemone hupehensis, which is now Eriocapitella hupehensis, is one of several species that I had been wanting to grow for a very long time. Like peony, goldenrod, Joe Pye weed, Indian paintbrush, beautyberry and fancy hybrids of clematis, they are prominent features of fancier gardens in other regions. Some of such species do not perform well here. Others are merely unpopular, but might perform well here if they get the chance. I see them all only in pictures, so can not distinguish what their respective situations are. The only anemones that I had ever encountered while young were sea anemones on nearby beaches. In college, I met poppy anemones, which we know merely as anemone, but found that they are not as reliably perennial as they are purported to be. Japanese anemone had been elusive, until I met a very established and perhaps invasive colony of it in an old landscape near Oakland less than fifteen years ago. I figured that if it can be as happy as it was in a relatively coastal climate, it could be happier here with a bit more chill during winter. Until then, I assumed that minimal chill was a limiting factor to their performance here. ‘Honorine Jobert’ seemed to be the epitome of single white Japanese anemone, but I had not seen any white cultivars, even those with double flowers, that were not alluring. Then, I discovered an unidentified cultivar of Japanese anemone on the edge of a rose garden here. It survives as a remnant of a preceding perennial garden, but does not perform well now that redwood roots have become so aggressive. Furthermore, its floral color is unimpressive. It is not white, but is not quite pink either. Heck, it is not even white blushed with pink. I do not know how to describe it. Initially, it seemed to be only slightly pinkish pale gray. Ick! This year, it seems to be slightly more pinkish than it had been, which makes it slightly less disappointing. However, now that I know it is here, I will not try any other Japanese anemone until I at least try to grow this one well. I am confident that if I relocate bits of it to a garden where it does not need to compete with other vegetation, it will bloom with a more appealing shade of pink. I will not mind that it is not white if it does that much. Then, if it can perform well, I will know that I can grow a white cultivar of anemone also. There is no rush though. Although white happens to be my favorite color, and Japanese anemone happens to excel at white, pink can be appealing also. This is my very first Japanese anemone, and regardless of how unimpressive it is now, I am pleased with it.

Sustainability Sometimes Needs Help

Some perennials naturally last longer than others.

            As much as I like to remind everyone of how easy it is to perpetuate many of their perennials for ever, and to share with their friends, neighbors, children, grandchildren, great grandchildren and so on, there are just some perennials that are not meant to last. I do not mean that they can not last; only that they are not as easy to sustain as others are. For most of these not so easy to sustain perennials, the original plants actually die completely, so will only be sustainable if replacement copies are propagated by cuttings or layers before the demise.

             Many of the very easy to grow daisies and daisy relatives are actually not as self sustaining as they should be. Clumping gazanias can actually rot out in the middle after a few years. Before this happens, it is rather easy to propagate replacement plants from division of mature clumps, or to take small cuttings, even though clumping gazanias do not often need to be pruned. Alternatively, side shoots can be layered (pressed into the soil to form roots) right next to parent clumps. Only a few replacements are necessary, but without them, clumping gazanias eventually die out.  

            Even trailing gazanias can eventually die out. Because they sometimes need to be pruned around the edges, there is a regular supply of material to make cuttings to patch bald spots. To get bigger cuttings, I actually like to delay edging until the plants look shabbier than they should around the edges; but my neighbors do not mind. (At least they do not tell me if they mind.)

            Shrubby marguerite daisies (not blue marguerites) and euryops likewise need to be replaced every few years. If there is enough space, outer stems that lay on the ground can be layered. It is best to bury each layered stem in a small hole, and then hold it down with a stone or brick. The layered plants may not be so symmetrical when the parent plants die out, but should fill out nicely. The fourteen euryops in the long park-strip in front of my home did not have enough space for layering, so died a slow, miserable and unsightly death until I finally removed them. If I had planned better, I would have taken cuttings to replace them.

            It is a surprise when pink breath of Heaven (Coleonema or Diosma pulchrum) or coyote brush dies suddenly, because they are really woody shrubs. (Although coyote brush is actually of the family Compositae like gazanias and daisies, etc.) Various ceanothus live longer, but not much longer. These woody shrubs are not so easy to layer, and quite difficult to root from cuttings, so often get replaced with new plants from the nursery, or different plants.

Six on Saturday: Old School

Bauhinia punctata, Tupidanthus calyptratus, Olmediella betschleriana and Oreopanax capitatus are a few species that Brent and I studied in school during the late 1980s, then encountered only very rarely afterward. Actually, neither of us have encountered a single specimen of Oreopanax capitatus since 1990. Brent managed to procure a Tupidanthus calyptratus for his driveway. I may eventually procure a Bauhinia punctata. Nowadays, I work with Cocculus laurifolius and Pittosporum crassifolium, which, previously, I had not seen since school. Agapanthus orientalis and Juniperus chinensis ‘Kaizuka’ could be just as old fashioned, but never really got scarce. Perhaps I should post more pictures of species here that are actually rare instead.

1. Agapanthus orientalis, lily of the Nile has been very popular and even common longer than anyone can remember, and still is. This picture of these divided and plugged shoots is here because I neglected to post it as I discussed them in Six on Saturday a month ago

2. Juniperus chinensis ‘Kaizuka’, Hollywood juniper was passe prior to when Brent and I were in school, but older specimens remain. They are like sculptural small cypress trees.

3. Cocculus laurifolius, laurel leaved snailseed is a species that we studied in school, but have seen in only a few situations since then. I happen to be acquainted with a few now.

4. Pittosporum crassifolium, karo is very similar in that regard. It might have been more popular a long time ago, but lost popularity as more interesting species were introduced.

5. Pittosporum crassifolium, karo produces annoyingly abundant and annoyingly sticky seeds. ‘Pittosporum’ translates to ‘pitchy seed’. If they germinate, they do not do it here.

6. Rhody’s Roady got its new license plate with the colors of 1969. ‘O’ is for ‘Occidentale’, which is Rhody’s last name. It is irrelevant to an Isuzu or a downtown shopping district.

Horridculture – Pseudo-Sustainability

This would not survive for long in the wild.

Sustainability is a good idea gone bad. Theoretically, it is commendable. Horticulturally, it involves growing species and cultivars that require minimal intervention or resources that they can not obtain naturally from their environment. In more extreme application, it can involve growing only native species, but not their cultivars that would not be naturally occurring, in order to limit interference with natural and endemic ecosystems.

Capitalism is a good idea too. Unfortunately though, it too often compromises other good ideas. It is how sustainability became a cheap fad, which now involves all sorts of artificial but marketable products and interventions that are contrary to its original intention. Regardless of their sources, water, fertilizers and amendments that are not provided by nature are unnatural. Container gardening infrastructure, irrigation systems, artificial illumination and really anything that is made of unnatural material are violations of sustainability that should be more obvious than they are.

‘Sustainability’ has become a buzzword for marketing.

There is certainly nothing wrong with appealing exotic vegetation with the garden or home. Almost all of the best and most popular vegetation is not native, and most of it relies on unnatural intervention and resources to perform as desired. However, it should be recognized for what it is, and not marketed as ‘sustainable’ if it is not.

This unusual cultivar of Aglaonema was unnaturally selected or developed from species that are native to tropical or subtropical climates of southeastern Asia. it grows primarily as a houseplant here because it is vulnerable to even very mild frost. It grew in artificial potting medium, within a plastic pot. It will always be reliant on artificial irrigation, and will perform better with unnatural application of fertilizer. It will always be less vigorous than greener cultivars because it lacks chlorophyll. Yet, it is marketed as ‘sustainable’.

Sustainability Is More Than A Fad

Vegetation that survives within untended gardens is truly sustainable.

Sustainability is a good idea gone bad. It is so often used as a marketing gimmick by those who actually have the least to gain from it. Really, landscapers and gardeners would not have much business if landscapes really were sustainable and able to function without their help. The best landscapes probably compromise between being as sustainable as possible with a few more conventional but less sustainable features to make them functional.

For example, lawn happens to be among the least sustainable of landscape features. It needs ridiculous volumes of water and continual maintenance, typically with gasoline powered mowers. Many lawns are gluttons of fertilizer. Yet, almost all landscapes have lawn of some sort. Lawns are certainly justifiable for children and dogs.

The trick is to use lawn like rugs for the landscape instead of like wall to wall carpeting. If possible, it should not be an all purpose ground cover for whatever area is not landscaped with something else. It should cover only areas that will get used as lawn.

Bedding annuals are likewise far from sustainable. They need too much water and work, and get replaced seasonally. Even those that sometimes naturalize where a bit of water is available, like sweet alyssum, godetia and nasturtium, really do not perform quite like more pampered bedding plants do.

The best way to see sustainability in action is not in the pretty pictures in the brochures of landscape companies with something to sell, but in the worst of landscapes. Plants that survive in abandoned landscapes where lawns and bedding plants have died off are obviously more sustainable.

Bottlebrush, oleander and various junipers and yuccas may be stigmatized as ‘gas station’ plants, but earned that stigma by being so resilient and sustainable. The many types of cotoneaster, manzanita, wild lilac and rockrose are also worth investigating, (although wild lilac and rockrose do not live as long as the other shrubbery does.) Redwood, California laurel, strawberry tree, incense cedar and many types of eucalyptus, oak , cypress and acacia are among the more sustainable of trees.

Sustainable Horticulture Should Be Sustainable

Lily of the Nile is sustainable!

There is no doubt about it. Weeds are sustainable. Otherwise, they would not be weeds. By definition, they grow where they are undesirable. Less sustainable vegetation should be less invasive. Also, it should be less resistant to eradication than most familiar weeds are. Unfortunately, also by definition, weeds are undesirable. They can not become fads.

Sustainable horticulture is a fad though. Unlike most fads, it is actually quite sensible. In theory, it is horticulture that requires as minimal intervention as possible. It excludes that which requires intensive or impractical cultivation. For example, native species that grow wild are sustainable. Tropical species that may survive only within greenhouses are not.

A problem with the sustainability fad is its marketability. ‘Sustainable’ and ‘Sustainability’ have become cliche buzzwords. They too often describe merchandise that is contrary to the fad. Realistically, genuine sustainability is unsustainable within profitable marketing. Truly sustainable merchandise would eliminate most of the need to ever purchase more.

Modern cultivars can qualify as ‘new and improved’ as they first become available. They are certainly new. However, their improvements may be questionable. Hybridization and extensive breeding can cause genetic deficiency. Even natural variegation compromises vigor. Seed is not true to type. Most aesthetic improvements are contrary to sustainability.

Native species are technically sustainable. Once established, they might survive without irrigation or other attention. Unfortunately though, some are not very adaptable to refined home gardens. Some are vulnerable to rot if nearby vegetation needs frequent irrigation. Some perform vigorously only for a few years. Several species are innately combustible.

Ironically, several of the most passe and old fashioned species are the most sustainable. That is why some of them became passe. Lily of the Nile can survive indefinitely. If it gets overgrown, it is easy to divide and relocate. It may be available for free from neighbors or friends. African iris, New Zealand flax, bergenia, most aloe and many yucca are similarly sustainable.

Six on Saturday: Memories II

Like my Six on Saturday from last week, these Six are described in reverse chronology of their approximate acquisition. My first two were acquired only within the last two years, so do not yet have much history with me. The last was actually acquired prior to the first of last week, and in conjunction with the second of last week, so is not exactly compliant with chronology. The fourth and sixth would have been more interesting in bloom. They all represent memories for me regardless, like almost all of the inhabitants of my simple garden. I notice them more at this time of year, while I work with them more.

1. 2021 Cycas revoluta, sago palm is another of several excellent items that I got for free on Craigslist. It got cut into too many pieces for relocation. All but a few are now rooted.

2. 2020 Gladiolus murielae, Abyssinian gladiolus is native to Abyssinia, not an abyss. It came here from the garden of a neighbor though. I had wanted to grow it for a few years.

3. 2015 Haemanthus albiflos, white blood lily came from a garden of an elderly client in Santa Clara who was quite fond of it. That is why I am so fond of it, even if unimpressed.

4. 2012 Lonicera albiflora, white honeysuckle is one of many souvenirs from Oklahoma. Most were seed. This and only a few others were live plants. It has grown very well here.

5. 1990 Chamaedorea seifrizii, bamboo palm was one of the first houseplants that I took from Brent when I moved into my apartment in town after the Loma Prieta Earthquake.

6. 1982 Pelargonium hortorum, zonal geranium without a zone gets big and weedy with hideously bright pink bloom. It grew wild with the crocosmia #2 of the Six for last week.

Six on Saturday: Memories

All but very few plants in my garden have history. Some have very extensive history, and a few have been with me for most of my life. Most were gifts. Some grew from pups, seed or cuttings that I collected from work, other gardens, or places that I travelled to. Almost nothing was purchased, although #1 of these six was a significant purchase for me while I was in high school. These Six are described in reverse chronology of their approximate acquisition. None are blooming now, but some get divided and planted now or a bit later through autumn. The roses will get pruned after defoliation. Only naked lady should not be disturbed until later.

1. 1983 Rosa hybrid, ‘Proud Land’ rose is the only one of these Six that I purchased, and also the only one that has not proliferated abundantly since acquisition. I got only three.

2. 1982 Montbretia masoniorum, crocosmia grew wild on a parcel in Montara where my Pa built his home. I do not know what variety it is. It is not as aggressive as most others.

3. 1980 Agapanthus orientalis, lily of the Nile has been with me since I removed it for a beloved neighbor who had brought it from a garden in Oakland about two decades prior.

4. 1979 Amaryllis belladonna, naked lady is from the homestead garden of my maternal maternal great grandparents in Hoot Owl Creek in Oklahoma, like my grape pop iris (5).

5. 1972 Iris pallida, Dalmatian iris, sweet iris or grape pop iris, came to my garden from the garden of my maternal maternal great grandparents, where it likely grew as an orris.

6. 1971 Rheum rhabarbarum, rhubarb likely grew in the garden of my paternal paternal great grandparents shortly after 1941. I got my copies of it before I got into kindergarten.

Watering Water Wise Plants

Excessive watering rots drought tolerant yarrow.

Native plants like coast live oak, valley oak, toyon, flannel bush, Western redbud and California lilac (ceanothus) are among the most resilient of plants as the weather gets dry and warm after spring. So are plants from similar climates, like bottlebrush, oleander, rockrose, grevillea, acacia and eucalyptus. They survive dry summers by dispersing their roots deeply into soil that does not get as desiccated as surface soil naturally does (without irrigation).

Ironically, these most resilient plants can also be difficult to work with while they are young. Because they rely on extensive root dispersion for survival, new plants that have not yet dispersed their roots can not survive long without regular watering. They only become tolerant to drought as their roots disperse into deeper soil.

However, because they are adapted to arid conditions, they do not like to be too damp for too long. Roots soon rot in soil that does not drain adequately between watering. They therefore need to be watered frequently, but not too frequently. Yes, that is as confusing as it sounds.

To make it even more confusing, these plants will need less watering as they mature and disperse their roots. Bottlebrush, oleander, contoneaster, hop bush, firethorn, grevillea and juniper can certainly tolerate more water than they really need; but wasting water is contrary to selecting drought tolerant plants to conserve water. Manzanita, coyote brush, rockrose, flannel bush and redbud may actually succumb to rot if watered too much. Even perennials like Pacific coast iris and yarrow can have problems.

Pine, oak, acacia and especially eucalyptus disperse their roots as soon as they can, so do not want to be confined in containers. It is therefore best to plant smaller young specimens than larger ones. #5 (5 gallon) eucalypti get established in the garden more efficiently than larger but more expensive #15 (15 gallon) trees. If #1 trees were available, they would be even better.

Daddy’s Garden

Truly sustainable plants are less lucrative to the nursery industries.

My rhubarb really has been around a while! My father’s father’s father and mother grew it quite some time ago, and shared some shoots of it with my father. He then shared it with my maternal grandmother, who shared it with her mother, another of my great grandmothers, who thought it was something really exotic. Along the way, it was undoubtedly shared with friends and neighbors all over the place.

My great grandparents with the original rhubarb also grew old varieties of grapes, oranges, lemons, walnuts and all sorts of vegetables. Their two (‘Carpathian’ English from Persia) walnut trees were remnants from an orchard that was already old before their home was new in 1940. The few ‘ornamental’ features of their garden included such old fashioned but resilient plants as junipers, callas, pelargoniums (geraniums), dahlias and roses. Yes, the stereotypical Italian American garden. My great grandfather even gave me my first nasturtium seeds.

My maternal grandfather likewise grew all sorts of traditional vegetables, as well as cherries, peaches, avocados, blackberries and raspberries. My grandmother competed for limited garden space to tend to her many roses, as well as lilacs and bearded iris that she got from her mother. My mother still grows a large herd of the original iris, several lilacs and a copy of the peach tree.

My very first experiences with gardening were in the old fashioned but remarkably sustainable gardens of my parents, grandparents and great grandparents. Such gardening with so many old fashioned plants would seem primitive by modern standards, but really demonstrates how sustainable proper horticulture is.

Of course, as a horticulturist, I work with all sorts of exotic plants and modern varieties. Although some are fun to work with, the best and most sustainable plants are the old classics and simpler ‘unimproved’ plants, especially those that can be propagated from seed, division or cuttings from established plants.

Many modern varieties of plants are more beneficial to the retail nursery industry than to home gardens, since they do not last too long. They are generally either not well suited to local climates, or are genetically weak from extensive breeding or mutation. (Many of the mutant characteristics that some varieties are selected for, such as variegated foliage or compact growth, compromise vigor.) As they come and go, more new plants are needed from nurseries to replace them. This is actually contrary to the sustainability fad that so many nurseries claim to promote.

Perhaps our parents know more about gardening and sustainability than we give them credit for.
