Rose Campion

80606Rarely planted but often found where the wildflowers grow, rose campion, Silene coronaria, has a way of sneaking in like California poppy or sweet alyssum do. It is so rarely planted that young plants are rarely available in nurseries. Seed is somewhat more available in nurseries, and quite available online. Although they self sow freely if allowed to go to seed, they are not really invasive.

The velvety gray foliage is pretty alone, and becomes a perfect backdrop for the surprisingly bright magenta, regal red or pure white flowers that bloom through early summer. Most of the foliage forms low mounds not much more than a foot wide, while flowering stems stand almost twice as tall. Flowers are ideal for cutting. Hummingbirds enjoy magenta and red flowers more than white.

Individual plants can last for a few years as short term perennials, but because they seed profusely enough to replace themselves annually, they are often grown as annuals, and pulled up before new seedlings appear. Those who last for a second year should probably be groomed. If seedlings are crowded, some can be pulled up and relocated while young. Rose campion wants full sun.

Naturalizing Might Be An Advantage

80606thumbOf course, to the plants who do it, naturalizing is an advantage. To the rest of us, it is often a problem. The advantage to the plants who do it is that they move into new territory, make themselves at home, and probably do quite well with the new place. The disadvantage to everyone else is that naturalizing plants may not play well with others, and consequently interfere with the ecosystem.

Most of the naturalizing plants whom we are aware of are aggressively invasive exotic (non-native) specie, such as Acacia dealbata, pampas grass, blue gum, broom and reed. They move in and compete with or exclude native vegetation. Some might interfere with native fauna as well. (All those monarch butterflies who swarm blue gum are ignoring specie who rely on them for pollination.)

Locally native plants can not naturalize because they are naturally there already. Therefore, all plants who naturalize are exotic. However, not all naturalized exotic specie are aggressively invasive. Some who can not survive without irrigation in the local chaparral climate may never get farther than being a weed in landscaped areas. Some bulbs may not spread from where they are planted.

Rose campion, sweet alyssum, cosmos, forget-me-not, four-o’-clock and nasturtium can replace themselves faster than they die out, but only where they get enough water. Some of the seedlings are likely to appear in situations where they are not wanted. Some might grow into situations where they might be desirable. There is no shame in allowing the desirable ones to continue growing.

Many of the most extensively bred garden varieties eventually revert to something more similar to their ancestors. For example, most of the fancier modern varieties of nasturtium, after a few generations, will bloom with more of the basic yellow and orange than they did when they were new. Eventually, almost all flowers will be yellow or orange. Such seedlings are known as ‘feral’, because they are more similar to the wild ancestry of nasturtium, than to the genetically unstable modern variety that was originally sown.

Memorial Day

P80527

Tomorrow is Memorial Day. Yesterday was the Felton Remembers Parade and Covered Bridge Festival, which is how Memorial Day is celebrated in Felton. It was a celebration worthy of Memorial Day, with plenty of music, crafts and expensive but unhealthful food to go with it. All that was lacking was that which is ‘memorial’. It seems that we have forgotten about that which we should never forget.

There were plenty of classic cars to provide memories of how stylish cars had been. There was a Boy Scout Troop to conduct the Flag Raising Ceremony at the main interchange of Highway 9 and Felton Empire Road to provide memories of when we still respected the American Flag and traditions associated with it. We were reminded of who our local politician are, and that we are still procuring funds for a new library, and that there are too many clubs for hateful women, and that the individual members of the motorcycle club get more done around here than everyone else combined (except for our local District Supervisor who provides the memories of what a public servant used to be.)

Felton Covered Bridge Park, the venue of the Covered Bridge Festival, is surrounded by memorial trees. All the redwood trees (which are of the cultivar ‘Soquel’, rather than wild trees) are memorial trees, sponsored by friends and families of the honored deceased. Some are outfitted with plaques. One was recently added. Another sweetgum tree is a memorial for Charlie, a very respected English bulldog. The small valley oak in an island in the parking lot is known simply as the Memorial Tree, to commemorate several who did not get their own tree. All the trees were there for the festivities, but only to provide shade and beauty.

Perhaps celebration is the best Memorial, or at least the best that such a large group can collectively participate in. Actually, the Covered Bridge Festival was exactly that, a ‘festival’ that merely coincided with the Felton Remembers Parade. It was not really a Memorial by design.

The big old Featherstone Tree at the center of town, and in the picture of the Felton Remembers Parade above, is not really a memorial tree, but does happen to be outfitted with a commemorative plaque for Mr. Featherstone who planted it, and has witnessed more parades on Highway 9 than anyone has.

The little Memorial Tree in Felton Covered Bridge Park, and in the picture below, was easier to ignore in the parking lot behind the mobile kitchens. I have written a few articles about it, beginning with this one –

Honeysuckle

P80526K

This is no ordinary honeysuckle. It is quite less than ordinary. It is not available in local nurseries. No one here wants it. Although it might be available from nurseries that provide native plants within the native range of this honeysuckle, most of those who find it in their garden probably do not want it there. After all, there are plenty of more desirable honeysuckles to grow. Some have more fragrant bloom. Some have more colorful bloom.

As you can see, this honeysuckle is not very impressive. It is about as shrubby as it is vining, and does not get very big. The small white flowers lack fragrance, and are not very abundant.

What I like about this honeysuckle is that it came all the way from Oklahoma. ( https://tonytomeo.wordpress.com/2017/11/19/oklahoma/ ) It is native there. I do not remember what honeysuckle it is at the moment. I brought it back with all sorts of seed and a few native plants that I obtained while there, including Arkansas yucca, Eastern red cedar and prickly pear. I can still remember sorting and packing some of the ‘specimens’ at a table outside a coffee shoppe on the bank of the Oklahoma River in downtown Oklahoma city, in Oklahoma County, in . . . Oklahoma.

When I grew rhododendrons, I knew people who bragged about rare cultivars that they and only a few of their friends and colleagues had obtained. Most were very pretty, with impressive bloom and bright color. Some were not so appealing; but no one wanted to say so. Sometimes, it seemed that the rarity of a cultivar was more important than any actual attributes.

I can remember many rare cultivars of rhododendron.

However, I know of none as rare as my honeysuckle from Oklahoma. I have the only one.

Six on Saturday: Elderberry +

 

It is only coincidence that all of the bloom for today happens to be white. Again, these are old pictures, from two weeks ago or so. The mock orange, Philadelphus lewisii, and black locust, Robinia pseudoacacia, finished bloom a while ago. Both were very fragrant.

I wanted to get these pictures of the ‘Black Lace’ elderberry, Sambucus nigra ‘Black Lace’, and the native blue elderberry, Sambucus cerulea, in bloom, not because they are remarkably pretty, but for comparison. Their more recent bloom has been more impressive, with wider floral trusses. The blue elderberry is very common here, and because common black elderberry are uncommon here, it is our standard elderberry. ‘Black lace’ is only rarely available in nurseries, and grown primarily for the dark foliage and nice bloom. However, some mail order catalogs describe it at a productive fruit ‘tree’, as if it is comparable to other elderberries. It came here as an ornamental. Fruit would be an added bonus. I am very interested to see how it compares to the native blue elderberry, which is excellently productive, particularly if cultivated. It is ideal for award winning jelly, even if it does not win the blue ribbon: https://tonytomeo.wordpress.com/2017/10/01/blue-ribbon/

Elderberry bloom is useful as well, although we have not used it for anything here. I prefer to leave the bloom to make more fruit. However, because there are so many around here, we could easily get a significant volume of bloom without significantly compromising the availability of fruit later on. Bloom can be battered and fried like fritters, or used in beverages. I will leave that work to someone else.

Clematis

70524There are so many different specie involved with the extensive breeding of the modern cultivars of clematis that they are not even assigned full Latin names. They are simply known as ‘clematis’ (without a specie name), with a respective cultivar name. Clematis X jackmanii is the oldest known hybrid, so the name is often applied to other hybrids, whether or not they are actually related.

The big broad flowers are abundant and spectacular this time of year, but unfortunately do not last long. Bloom finishes before the weather gets much warmer, leaving unimpressively rustic foliage on wiry vines. The vines might reach ground floor eaves, and are just the right size for small gate arbors. If necessary, old plants can be lightly groomed of twiggy growth while bare through winter.

Flowers are rich shades of blue, purple, red, pink or white. Many are bi-colored, and some have ruffled centers. During full boom, there may be more flowers than foliage visible. Foliage is a dark shade of olive green, with a dull matte finish, which is actually a perfect background for the rich color of the bloom. Roots like rich, moist and cool soil, while the vines climb into sunnier situations.

FLUX

P80523This unhappy native white alder, Alnus rhombifolia, had been deteriorating for quite a while. White alders do not last long even in the wild. A few nearby have already been removed. This one is next. They were nice and shady when the landscape was new. Nicely maturing sycamores and a bigleaf maple can take over for this one now.

As bad as it looks, this nasty stain had nothing to do with the imminent doom of this tree. It developed only recently, and very quickly. It is not nearly as bad as it looks. If the tree were not to be removed, it could survive with this problem for quite a while. Other healthier trees can live with it for many years or indefinitely, and some actually recover.

It is ‘flux’. More specifically, it is slime flux, which is also known as bacterial wetwood. The obvious symptoms are this unsightly bleeding and staining. A less obvious symptom is the swelling that caused the fissure in the bark from which the unsightly fluid is draining. The fluid can smell nasty!

Furrows in the bark develop naturally as the trunk expands over many years. They do not penetrate through the bark into the cambium below.

Fissures are fractures that penetrate through the bark and into the cambium. The fissure in these pictures developed so recently that the orange interior of the bark has not oxidized to tan or gray yet. The fissure is about six inches long, and slightly lower than a doorknob.

Even for healthy trees, there is no remedy for slime flux infection. It can only be left to do whatever is going to do. It can accelerate internal decay, but is otherwise not as detrimental to the health of an infected tree as it would seem to be.P80523+P80523++

Flowers For Home And Garden

70524thumbThere is a difference. Hybrid tea and grandiflora roses were bred to be excellent cut flowers for the home. They bloom on long stems, and last well once cut. However, the rigid and thorny plants that produce these excellent blooms are realistically not much to look at. Floribunda, polyantha and climbing roses are more of a compromise with less ideal (perhaps) flowers on friendlier plants.

Conversely, bearded iris are spectacular while blooming out in the garden, but do not last so well as cut flowers. As colorful as they are, they perform best while still attached to the plants that produced them. Fading flowers might be groomed away from flowers that continue to bloom later, but are not a serious problem if allowed to linger. The garden is more forgiving than the home.

Where space allows, rose gardens or cutting gardens are areas devoted to the production of flowers for cutting and bringing into the home. Like vegetable gardens, cutting gardens might be hedged, fenced or partly concealed from the rest of the landscape. No one minds if the utilitarian plants within get deprived of their flowers, or need to be staked or caged like big tomato plants.

Taller and bulkier varieties of dahlia, delphinium, lily, Peruvian lily (alstroemeria) or sunflower that might be to big and awkward elsewhere in the garden can be right at home in a cutting garden. Compact and more prolific varieties of the same flowers work better in more prominent parts of the garden, and if prolific enough, can also provide flowers (although less spectacular) for cutting.

There are very few rules in regard to cut flowers. Many of us bring in bearded iris or daylily, even though they may not last more than a day. The buds below the flowers might bloom afterward. Blooming clematis vine, nasturtium (on or off stem), lily-of-the-Nile, zonal geranium, bougainvillea, bottlebrush, crape myrtle and even flower stalks of New Zealand flax, are all worthy cut flowers for anyone wanting to try them, especially if the garden provides enough to spare.70524thumb+

Cherry Laurel

80530There is a reason why the most popular specie for frequently shorn formal hedges have small leaves and finely textured foliage. Technically, a formal hedge of cherry laurel, Prunus laurocerasus, can be shorn as well, but should be shorn only once or twice annually, and then allowed to fluff back out. Otherwise, the big leaves get shredded as quickly as they recover from previous shearing.

If pruned more frequently, hand pruning works best, and is not as tedious as it sounds. Informal pruning is even easier, and is done primarily to prevent hedges from getting to deep (from front to back), and to prevent individual shrubs from dominating or subordinating. Pruning also eliminates most of the abundant summer bloom of upright trusses of thirty or so tiny creamy white flowers.

Cherry laurel is densely foliated and quite stout, even without shearing or pruning, and can eventually but rarely get thirty feet tall! The glossy evergreen leaves are about three inches long. There happens to be a few cultivars, including one that is variegated with light yellow, and others that are compact dwarfs. (Prunus caroliniana is different species that is also known as cherry laurel.)

Overgrown Shrubbery Becomes Small Trees

80530thumbThose of us with ‘maintenance gardeners’ are likely aware of how rare it is to find someone who knows how to maintain hedges properly. It seemed so simple years ago. Several identical plants could simply be planted in a row, and then somewhat regularly shorn for confinement to a prescribed space. They were not allowed to exceed a specific height or width for long between shearing.

Formal hedges are now passe. They do not conform to modern landscape style. No one wants to maintain their formality anyway. If a gap develops, it is likely to be filled with a different cultivar or species that is not identical to the rest of the hedge, merely because it happened to be available at the nursery. Feral or invading shrubs, vines or even trees get shorn right into the whole mess.

Then there is the problem with bloat. Rather than staying confined, hedges typically get slightly larger with each shearing. What is worst is that most of the extra bulk is high up and shading lower growth, causing it to grow slower. Hedges eventually develop that all too familiar top-heavy appearance, and encroach into otherwise usable space that they were designed to provide privacy for.

There are few simple options for hedges and shorn shrubbery that have gotten too big for their space. Some can be renovated and cut back beyond their outer surfaces, but recovery will take a bit of time, and can not fix unmatched plants. However, such restoration is likely better than replacement. Just like for a new hedge, feral and invading vegetation must be removed in the process.

Another option is to completely change the form of improperly shorn shrubbery to small trees. This can be done with individual shrubs, or a few selected remnants of an otherwise removed hedge. Cherry laurel, photinia, bottlebrush, tea tree, privet, various pittosporums and many other large hedge shrubs work quite nicely. Rather than getting pruned back into submission, the lower growth gets pruned away to expose sculptural trunks within, and the upper growth gets pruned only for clearance above.
