Wildflowers On The Wild Side

Some wildflowers bloom in shady forests.

Warm season annuals are more varied than cool season annuals for one simple reason. Spring and early summer are the best time for bloom. Afterward, there is plenty of time for seed to develop, prior to cool winter weather. Obviously, most flowers want to exploit this schedule. This includes wildflowers, particularly in regional chaparral or desert climates.

Wildflowers are in more of a rush to bloom for early spring here because summer is arid. They could be more susceptible to premature desiccation later. They last longer and can bloom later in home gardens with irrigation. Actually though, not all wildflowers bloom for early spring. Some bloom for autumn or winter. A few bloom for summer, generally briefly.

There is no explicit definition for wildflowers. Western redbud and the various ceanothus are technically native wildflowers. Yet, they grow as large shrubbery or even small trees. Most popular wildflowers are annuals. A few are biennials or perennials. Some perennial sorts must mature for more than a year before they bloom well. Some are very persistent.

Technically, wildflowers should be locally native, and observable directly within the wild. Realistically, this expectation is unrealistic. Many of the most colorful, like perennial pea, are naturalized exotic species. Most wildflower seed mixes include random species from elsewhere. Some are regionally specific, but to other regions and very different climates.

California poppy and various lupine are the most popular and familiar native wildflowers. Douglas iris, yarrow and clarkia are about as practical for cultivated home gardens. Bush poppy and monkey flower more appropriate to rustic landscapes beyond home gardens. Many wildflowers need aggressive maintenance, such as cutting back after their season.

Seed of most annual and perennial wildflowers prefers to be in a garden by late autumn. It can then settle in through cool and rainy winter weather to grow and bloom about now. With watering after the winter rainy season, several might start now to bloom for summer. Some of the more sustainable species can disperse seed for another wildflower season.

Canna

Cannas are as foliar as floral.

Not many summery bulbs provide as much immediate gratification as Canna. They grow very fast as soon as the weather begins to warm at the end of winter. They could become a bit too invasively vigorous for some situations. Canna are almost too easy to propagate by division. They probably perform better with annual thinning, preferably while dormant.

Dormant canna rhizomes are now available from nurseries. Potted specimens should be available a bit later. Canna, though, might be as available from friends or neighbors who grow too many. They crave frequent irrigation, and can inhabit riparian situations such as ponds. Although they are not too discriminating about soil, the prefer organically rich soil.

Canna foliage is about as lush and striking as its bloom. It can be green, various shades of bronze or variegated with white, yellow or bronze. Flowers can be thin and ribbony, or big and billowy. Floral color is various hues of yellow, orange, red, pink, or rarely creamy white. Flowers are commonly spotty or blotchy. Some canna grow higher than eight feet. Dwarf cultivars bloom splendidly without growing taller than two feet.

Pork & Beans

If it appears to be related to burrow’s tail, it is because pork & beans is the same genus.

The tender succulent foliage of pork and beans, Sedum rubrotinctum, is as squishy as it appears to be, so is safest where it will not be disturbed. Although it sprawls around without getting much deeper than six inches, it does not fill in reliably enough to be a real ground cover over a large area anyway. It can instead add color and texture in small doses between larger plants or stones. It is a nice addition to urns of mixed perennials, rock gardens and dish gardens. It propagates very easily from stem cuttings or even leaves that break off, so can be tucked into gaps in stone walls.

The plump three quarter inch long leaves resemble jelly beans more than pork and beans, since they are green where shaded. More exposed foliage is more bronzy red or brown, especially at the tips. Small clusters of tiny yellowish flowers are held above the foliage on reddish brown stems in spring.

Horridculture – Pseudopalm

Strelitzia nicolai, is giant bird of Paradise. Unlike the more familiar bird of Paradise, with basal foliage and its distinctive orange flowers, this species develops several tall trunks and less colorful but interestingly large white flowers. We recycled several into one of the landscapes here from a home garden in Morgan Hill about two years ago. Originally, they were three somewhat mature groups, with rather tall trunks. Then, they were divided into individual trunks and pups. Ultimately about sixteen were installed into the landscape, with a few spare pups canned as spares, just in case some of the others do not recover from their division. I predicted that those with tall trunks would not last long before replacing themselves with basal growth, and then shedding their unusually tall trunks. Not only are they not developing basal growth yet, but their upper foliage on top of their lanky tall trunks is actually growing and developing into new foliar canopies. They sort of look like silly palm trees that are getting less silly as they continue to grow. I mean that they actually look rather appealing, and probably look more appealing to those who do not know what they should look like. They seem to be pretending to be faux palm trees. I can do nothing about their behavior, and even if I could, I would not. I want to see what they do next. I suspect that they will eventually perform as expected. I also suspect that, because they are already so tall, that, for as long as they retain it, their upper foliage will never be as lush as it would be if lower. That is normal for the species, and how those who maintain such specimens know when to cull the taller trunks by cutting them to the ground.

Coral Bells

Coral bell foliage is as pretty as its delicate flowers for which it is named.

Even though their delicate trusses of tiny hanging flowers on one or two foot tall wiry stems make good cut flowers and attract hummingbirds in spring and early summer, coral bells, Heuchera micrantha, is more often grown for its colorful foliage. Contrary to their common name, the flowers (of this species) are more often pale or greenish white anyway. Their foliage can be all sorts of shades of green, gold, tan, brown, bronze, and purplish. The rounded and lobed leaves have somewhat raspy tomentum (hairs) and can be about two and a half inches wide. ‘Ruffles’ has more ruffled and deeply lobed leaves. ‘Palace Purple’ is a very popular cultivar with distinctive deep bronze or purplish foliage.

Mature plants can be divided in spring to make more plants every few years or so. Where protected from frost, division can be done in late autumn. Coral bells can also be propagated by cuttings. Rich soil and good exposure are preferred; but partial shade is best in warm spots.

Dusty Miller

Such silvery foliage contrasts exquisitely with bronze foliage.

The relaxed trusses of small yellow composite (daisy-like) flowers of dusty miller, Senecio cineraria, can bloom at any time except when winter gets too cold. They are still blooming now. Yet, who cares? Dusty miller is grown more for its fuzzy white foliage than for bloom. It actually looks best and fluffier if occasionally shorn and pruned to remove blooming stems before they bloom. Individual leaves are intricately lobed. Mature plants get taller and wider than two feet. Dusty miller likes full sun exposure, good drainage and moderate water. Too much water causes rot and discoloration.

Hellebore

Hellebore is popular within cooler climates.

Where winters are too cool or damp for much else to bloom, hellebore are more popular. The most popular are Helleborus X hybridus, which are hybrids of a few similar species. Most are direct descendants of Helleborus orientalis. They are more resilient to frost than to arid warmth during summer. Actually, that is very likely why they are less popular here.

Locally, hellebore are useful for cool, damp or partly shady situations. However, they are not as substantial as ferns. Also, they can get a bit wimpy as the weather warms through summer. Although evergreen, they shed some of their older yellowing foliage. They grow most during late autumn, winter and perhaps early spring. They crave richly organic soil.

Floral color is typically subdued but interesting. Most common hellebore flowers are pale pink or almost grayish white with spots. Alternatively, they can be rusty red, maroon, pale green, yellow, gray or almost black. Some exhibit more or less spots, blotches, stripes or picotee edges. Double flowers are rufflier than single flowers are. All hellebore are toxic, and for some, can cause dermatitis.

Semperflorens Begonia

Some of us learned this as fibrous begonia.

From spring until autumn, semperflorens begonia, which is also known as fibrous, bedding or wax, begonia, is a warm season annual. They actually start to deteriorate as the weather gets cool this time of year. However, they do not necessarily need to be pulled out as their season ends. In sheltered locations or with protection from frost, they actually survive through winter as perennials. They are so easy to propagate by cuttings or division of overgrown plants that tired older plants can replace themselves with their own babies before they get too ugly.

The small flowers of semperflorens begonia can be white, red, or various shades of pink in between. Foliage is more often green or bronze, but can be reddish or variegated. The largest plants get only a foot tall. Denser dwarf types are half as tall. Semperflorens begonia likes rich soil and regular watering (when it is not raining). They prefer partial shade, but will take full sun if mixed with other plants that keep things cool and humid.

Santa Cruz II

Begonia boliviensis ‘Santa Cruz’

Begonia boliviensis ‘Santa Cruz’ is significantly bigger than it was when I wrote about it three months ago. If I had known that it would have performed so well, I would have groomed it for better form. It grew upright at first. I just let it do so because I wanted to make a cutting from the tip when it got pruned back. However, because it leaned over and branched as it should, it did not get pruned back. It could have developed a better and lower form if I had tended to it better, but I am too pleased with it now to complain that it is a bit more upright than it should be. I do not mind that I did not get a cutting from the primary stem that I did not cut back because there are now many more stems that I can get cuttings from, simply be grooming out a small bit of superfluous growth from within. I could get many more than I want if I were to actually prune this specimen back for winter. It is getting to be too exemplary to cut back for winter, though. Nor do I want to leave it out to get frosted, as I might do with other begonias. The horticulturist who procured it will shelter it from frost, and perhaps groom it a bit after winter, but otherwise try to retain as much of this growth as possible for a head start next spring. I am curious to see what it does. Will it shed most of this growth as it resumes growth from below next spring; or will it grow from near the tips of where it stopped growing this year? I did not expect to be so impressed by this modern cultivar of Begonia.

Karpooravalli

Karpooravalli bananas after removal of their edible male flowers below.

Pronunciation is only slightly easier than when I first tried to read it. Spelling still necessitates cheating, which I do not feel at all guilty about. Karpooravalli is a big name! I must get acquainted with it though, since it will likely be with me for the rest of my life.

Yes, it is another cultivar of banana, which is something else that I do not feel at all guilty about. I have no intention of retaining all of the other twenty or so cultivars that are already here. In the future, I will likely give away most of them to colleagues, without retaining pups. I actually already have plans to install at work the two that are least likely to produce edible fruit, and never grow either in my own garden again.

Karpooravalli banana pups

These four new pups of Karpooravalli arrived last Monday, just two days after eight unidentified pupping pups and a single pup of ‘Blue Java’ which is also known as the ‘Ice Cream’ banana. Like these previously most recent acquisitions, as well as another ‘Blue Java’ pup and another unidentified pup that were acquired together last year, these four pups of Karpooravalli are from a private garden. All of the other cultivars here are from nurseries, and most were tissue culture plugs that never actually grew in soil.

That is the dilemma. Cultivars from nurseries are expendable. I can give them away without retaining any copies and not miss them. However, cultivars from private gardens have history, even if I am unaware of it. They are important to someone.

I can give away the recently acquired pup of ‘Blue Java’ only because another pup of it from another important source is already established here, and I knew when I took it that it would not be staying. Also, I can give away almost all of the other unidentified pups that came with it because there are already too many to retain. However, I will retain at least one of them because I know that the cultivar was important to the person who shared it. Likewise, I will retain my first copy of ‘Blue Java’ and the unidentified pup that came with it because they are important to the person who shared them.

Karpooravalli is fortunately one of the more reliably productive cultivars here, and provides sweet fruit with remarkably rich flavor. It is gratifying to know this now because I will grow it for as long as I can tend the garden. This particular Karpooravalli is very important to the person who grew it in her garden for a few decades before sharing it with me, so it is important to me now. I know that I will eventually need to share it with others as it multiplies in the future, but I will prefer to share it with those who respect its importance.

Before I was in kindergarten, I acquired my rhubarb from my paternal paternal great grandfather, and my Dalmatian iris from my maternal maternal great grandmother. Both are growing well in my garden now, and always will. I acquired my common lily of the Nile and the first of my common zonal geranium a few years later. Much of what inhabits my garden now has been with me for many years. Yet, I acquired my first Japanese iris, persicaria and goldenrod as recently as late last winter from Tangly Cottage Gardening. Perhaps it is never too late to start another important tradition.
