4:00

Mirabilis jalapa is known more commonly as four o’clock. It is spelled with letters rather than as 4:00 with numbers. This refers to the time in the afternoon when its bloom should be at its best. These pictures were taken prior to nine in the morning though. Apparently, it does not adhere to a strict schedule. I took these pictures because I was so impressed with the performance of these particular specimens. Those with yellow bloom above are so large that I came from across the road to confirm their identity. I do not expect this species to grow so large. They are about as big as small oleander! Those with white and pink bloom below are actually the same plant. The species commonly blooms with flowers of different colors, but such colors are typically not so divergent as clear bright pink and clear white. They are more typically blotched with colors of each other, such as white flowers with a few pink blotches in conjunction with pink flowers with a few white blotches. This species is somewhat naturalized here, but politely so. Although it generates copious seed, it is not migrating very far from where it is established.

Poor Man’s Rhododendron

Poor man’s rhododendrons is less colorful but more perennial than the more popular busy Lizzie Impatiens walleriana.

The nursery industry is so innately unsatisfactorily lucrative, that to us nurserymen, a ‘poor man’s rhododendron’ is any rhododendron that we grow. To everyone else, it is Imaptiens sodenii, a tender perennial that gets to six feet tall and wide or even larger on plump, softly succulent stems. It succumbs to even mild frost in winter, but regenerates rapidly by summer. It prefers partial shade, and can roast if too exposed to direct sunlight on warm days. Too much shade is rarely a problem.

The two inch wide flowers are typically very pale shades of pink, lavender or slightly blushed white. At least one modern variety has brighter white flowers with reddish pink centers. Bloom continues as long as weather is warm. The seed capsules are not much to look at, but explode to disperse their seeds when disturbed. The soft, rich green leaves are about three to six inches long.

Ice Plant

Other types of ice plant bloom with different colors.

The bright orange, inch and a half wide flowers of Lampranthus aurantiacus, a type of ice plant, should bloom between winter and spring, but a few are brightening my garden right now. This bright yellow flower in the picture is that of the variety ‘Glaucus’, which I grew from a cutting last year. My single low mounding plant is about a foot wide now and will eventually spread to about two feet wide, and can get about a foot deep. Stems can root where they lay, forming new plants that will spread farther. To accelerate the spread, more plants are very easy to propagate from small cuttings. Lampranthus aurantiacus has narrow, inch long leaves, and a relatively shrubby basal branch structure.

Perennial Gladiolus

Gladiolus papilio, butterfly gladiolus

Gladiolus papilio, butterfly gladiolus has been performing very well, and, unlike the more common fancy hybrid gladiolus, it has been very reliably perennial. It multiplies and migrates like a wildflower. I know that I brag about it more than I should, and I just posted a picture of it for Six on Saturday last Saturday, but it happens to be one of my favorite perennials now. It was a gift from Tangly Cottage Gardening in the autumn of 2018, almost six years ago. Prior to that, I had been wanting to grow perennial gladiolus for quite a while, although I was not familiar with such species. I was only familiar with the common fancy hybrid sorts, which are generally not reliably perennial. Gladiolus murielae, Abyssinian gladiolus that arrived a few years ago as a gift from a neighbor may eventually inhabit a different portion of the same landscape that the butterfly gladiolus inhabits. It neither multiplies nor migrates as much as the butterfly gladiolus, and is a bit more garish in bloom, but is both reliably perennial and compatible with wildflowers, and technically, is probably more appropriate to that particular refined landscape. Various cultivars of Watsonia, bugle lily, most of which also came from Tangly Cottage Gardening, could also inhabit the same landscape. There is no rush to decide anytime soon, and the refined landscapes at work are constantly evolving. Within my home garden, I can be less concerned with how visually compatible some of such species and cultivars are, and be more concerned with growing what I enjoy. After all, that is how I acquire so many odd species and cultivars with so much history and from so many important gardens, and even from so many natural ecosystems. It is what makes my home garden so important to me.

Sweet Spot

Saccharum officinarum ‘Pele’s Smoke’ sugarcane

‘Pele’s Smoke’ sugarcane has grown enough for installation into the landscapes. I am not certain how happy they will be here through winter, but we will find out. Frost is mild here, but is supposedly enough to kill them to the ground. I expect that. Even if they do not die to the ground, I would prefer to cut them down by the end of winter regardless. Survival of their basal growth is more of a concern. I want them to regenerate next spring. It is difficult to imagine a species as vigorous as this being so vulnerable to the locally mild frost, but all the information that I find about it insists that it is marginal here. There are so many canned specimens that it would be no problem to shelter some through winter to replace any that do not survive in the landscapes. Later, if they get depleted, it would be no problem to take cuttings from those in the landscapes in autumn, and shelter them through winter to put back into the landscapes in spring. However, that is just too much unnatural intervention for me. If they are not happy here, they I do not want to force them. I enjoyed growing them while I did. I got the cuttings from grooming a specimen in Brent’s garden. I was not very careful with them, and did not process them very efficiently because I knew that I would get more than I could accommodate. Ultimately, after sharing a few with friends and neighbors who are aware of the risks, thirty new specimens remain here. Fifteen are in #1 can, including the first three that were just installed into the landscapes. Another fifteen are in four inch pots, which is annoying one less than a full flat of sixteen.

Six on Saturday: Glad

Butterfly gladiolus will not bloom for a while. Abyssinian gladiolus may not bloom at all. Hybrid gladiolus, though, are already finishing. I got these few pictures while I can, and will likely get pictures of butterfly gladiolus as they bloom later. I am glad to do so. They are my favorite gladiolus. They are more like wildflowers than overly bred hybrids. Also, they are very reliably perennial. I hope that the Abyssinian gladiolus perform also. They are also supposedly reliably perennial, but are not in a very good situation here. I should relocate them, perhaps closer to where the butterfly gladiolus are so happy. The hybrids are earning my appreciation too. I was not aware that they had potential to be perennial.

1. Gladiolus papilio, butterfly gladiolus is my favorite, because it is from Tangly Cottage Gardening, is approved by Skooter, is reliably perennial, and it blooms like a wildflower.

2. Its foliage is rather grassy, which is more compatible with other wildflowers than wide leaves of more garish hybrid gladiolus. The corms multiply and migrate quite efficiently.

3. Gladiolus murielae, Abyssinian gladiolus is my second favorite, even while it is not so much to see. It is a gift from a neighbor. It should bloom for autumn, but I have doubts.

4. Hybrid gladiolus are the most colorful, but are not reliably perennial. However, these and two others have been blooming well here for several years, and actually multiplying.

5. This orange with yellow hybrid gladiolus was one of the first two to bloom again after a few years of producing only foliage. The yellow gladiolus joined them a few years later.

6. This purple hybrid gladiolus is the other of the first pair to resume bloom, although it does not multiply as much as the yellow gladiolus that resumed bloom a few years later.

Thrift

Thrift performs well in coastal climates.

When I see common thrift, Armeria maritima, in nurseries now, I wonder what such a diminutive perennial would be useful for. Their densely compact mounds of narrow evergreen leaves rarely get more than four inches deep, and take their time spreading to less than a foot wide. Then I remember how thrift visually softened the straight edges of my father’s brick patio and retaining walls, and fit so nicely into the tight spots. If allowed to do so, thrift creeps slowly over edges of pavement and stepping stones, but is not too eager to overwhelm them.

If it eventually gets overgrown, thrift is easily cut back to the edge of pavement at the end of winter, and will green over its raw edge by spring. The bits and pieces that are left over from cutting back the edges can be plugged back into other areas and will eventually develop roots if initially watered regularly. Once established, thrift stays healthier if allowed to dry somewhat between watering. Bald spots that may naturally come and go as mature plants die out in the center and then regenerate fill in faster if outer edges get cut back.

The dense round clusters of tiny flowers stand above the foliage on bare stems about four to eight inches high. The flowers are almost always bright pink, but are sometimes white or reddish pink. Bloom is most profuse in spring and may continue sporadically all year.

Perennial Annuals

New Guinea impatiens (with ivy geranium) from last year.

Annuals complete their entire lifespans within a single year.

Perennials survive for more than a single year.

Biennials grow vegetatively during their first year, and then bloom, disperse seed and die during their second year, but that is another story.

Most species that are appreciated as annuals here actually have potential to be perennials, even if only short term perennials. They are only replaced annually because it is easier than maintaining them through their dormant season.

For example, busy Lizzy is a warm season annual that gets installed for spring and replaced with cool season annuals for autumn. However, if cut back and sheltered from frost, it can survive through winter to perform for the following spring and summer. Actually, it can survive perennially like this for quite a few years, and as it ultimately deteriorates, it can replace itself with its own cuttings or layered stems.

Brent did this with New Guinea impatiens from last year. He neglected to replace them for winter (which is quite brief there), and then noticed that they resumed growth as winter ended. Now, they are huge and even more spectacularly florific than they were last summer.

The picture above shows where I camp out in his backyard when I go to Southern California. Most of the white bloom to the right is actually ivy geranium that cascades below the New Guinea impatiens, but most of the white bloom to the left is New Guinea impatiens above ivy geranium. (White on white was not quite as monotonous when each of the two species maintained its distinct form last year.)

Small terrace at the western margin of the garden.

This other pair of potted dwarf Alberta spruce surrounded with the same New Guinea impatiens above, with a close up below, flanks the steps to a small terrace at far western margin of the garden.

These New Guinea impatiens are huge because they resumed growth from last year.

Butterfly Amaryllis

Hippeastrum papilio, butterfly amaryllis is an uncommon and weirdly epiphytic amaryllis. It may not be as pretty as the countless more colorful hybrids of the genus, but it is more reliably perennial. All of the few specimens that I have observed within home gardens are potted or in the ground, either because they are easier to grow that way, or because those who grow them are not aware that they are epiphytic. After all, that is quite weird.

This specimen, from my Six on Saturday post earlier this morning, is blooming in Brent’s garden. As I mentioned earlier, Brent did not know what it was when he acquired it from a neighbor who left it with him when she relocated. I know that it does not look like much in this picture, but that is only because Brent is an idiot, and takes bad pictures. I intend to get a copy of this butterfly amaryllis for my garden, and may try to grow it epiphytically.

I find this species to be more appealing than prettier hybrids, both because it is reliably perennial, and because it is a simple species rather than a hybrid. This is also why I dug a few naturalized Crinum bulbispermum, Orange River lily bulbs for my garden. They are none too pretty, but will last forever. The same applies to Amaryllis belladonna, naked lady, but they are a bit too prolific and common to not potentially qualify as a weed. Their bright pink floral color can be a bit obnoxious anyway. But of course, that is why I was so very pleased to find a bulb that bloomed white, which is my favorite color. It is multiplying nicely here now, just like I know the butterfly amaryllis will once I get a fresh copy of it.

Bearded Iris

Bearded iris blooms after spring bulbs.

There may be no other flowers that exhibit such a diverse range of floral colors. Bearded iris, Iris X germanica, classifies as a hybrid of Iris pallida and Iris variegata. The genus of Iris derives its name from the Greek word for rainbow. As the name implies, it includes all colors of the spectrum. Floral form, height and, for some, fragrance is also quite variable.

About sixty thousand cultivars of bearded iris are supposedly documentable. It is difficult to estimate how many lack documentation. The smaller miniature cultivars are only a few inches tall. The tallest cultivars may grow four feet tall. Although they classify as summer bulbs, they are fleshy rhizomes that bloom for spring. Some will bloom again for autumn.

Bearded iris multiply whether or not anyone wants them to. Their rhizomes branch in two directions after bloom. Besides that, side shoots develop randomly from plump rhizomes. Congested rhizomes may bloom less. Division during summer promotes bloom. Division may happen annually or every few years. Bearded iris prefer sunny and warm exposure.
