Native Species Are Naturally Natural

California poppy is a common wildflower.

Vegetation has always been here. Wildlands outside of urban development demonstrate that noplace is or was without it. Native species lived here before any home gardens did. Whether intentionally or unintentionally, some of it still does. Some sneaks in like weeds. Some arrives by invitation. A few old trees never left as the area around them developed.

Native species perform well locally because they are adapted to local climates and soils. It is all very natural to them. In fact, many dislike major modifications to their climates and soils. Although most tolerate or even appreciate a bit of supplemental irrigation, some do not. Many rot if irrigation is too generous. Also, many do not want much soil amendment.

Some native species might be a bit too natural, though. Because they are from chaparral climates, they can get somewhat scraggly by summer. It is not because of a lack of water or other environmental deficiency. It is their natural behavior, and how they survive in the wild. Many wildflowers that bloom so well for spring are completely dormant by summer.

The advantage to this is that almost all native species do not demand much water. Many want none at all. Once established, they get all they need from natural rainfall. Therefore, landscapes of mostly or exclusively native species conserve water. Since native species are adapted to endemic soil, they require no fertilizer either. They are quite conservative.

California poppy, which is the State Flower of California, is a very familiar native annual. Unlike other native species, it appreciates supplemental irrigation after the rainy season. It typically blooms only for spring, but may bloom into summer with occasional irrigation. Sky lupine is another native annual that blooms for spring, with contrasting blue flowers.

Various salvias, bush lupines, penstemons, irises and grasses are native perennials. So are sticky monkey flower, Oregon grape, tree anemone and tree poppy. Toyon, silk tassel and various California lilacs are native shrubbery. So are flannel bush, coyote brush and coffeeberry. California sycamore, coast live oak and redwoods are common native trees.

Six on Saturday: More

More flowers seem to be in order. The six that I posted pictures of last week got so much extra attention.

1. Gerbera jamesonii, Transvaal daisy, along with the columbine below, was observed in a nursery. It is a long story. To be brief, neither was within the landscapes or my garden.

2. Aquilegia X hybrida, columbine is the State Flower of Colorado, but also is the colors of the Flag of Greece. Perhaps that is too much trivia. It is elegant and pretty regardless.

3. Sisyrinchium angustifolium, blue eyed grass grows wild here. This one happens to be in my driveway. Its proliferation exceeds its intellect. It might otherwise soon be extinct.

4. Chaenomeles speciosa ‘Orange Storm’ flowering quince is appealing only because it is a flowering quince. I am unimpressed by its fancy breeding and orangish red garishness.

5. Prunus persica var. nucipersica ‘Fantasia’ nectarine is more respectable since it is not fruitless, and also since it is among the most popular cultivars of the Santa Clara Valley.

6. Prunus salicina ‘Satsuma’ plum is not as popular as ‘Santa Rosa’ plum is, but it is very traditional among those who are familiar with it. It is not quite as tart as ‘Santa Rosa’ is.

Flowering Apricot

Flowering apricot blooms almost too early.

Flowering cherries are not necessarily the first of the flowering trees to bloom. Flowering apricot, Prunus mume, is even earlier than all but the winter flowering cherry. Many have bloomed already, and as early as a month ago. The latest will bloom soon. Their flowers are more resilient to weather than those of flowering cherry. However, they bloom briefly.

Although generally fruitless, a few cultivars produce fruit for pickling, as umeboshi. Such fruit, without pickling, is rather unpalatable. Some cultivars of flowering apricot are useful as understock for related trees. Actually, some local flowering apricot trees grew from the roots of other flowering plums. New trees are very rarely available from nurseries locally.

Mature flowering apricot trees are ten to nearly twenty feet tall and almost as broad. They bloom before they foliate. Abundant bloom on big trees can be mildly fragrant. Individual flowers are about an inch wide. They are pastel pink, but can be white or deep rosy pink. Blooming stems can be exquisite as cut flowers, although they may not last for very long. Such stems are a traditional component of ikebana.

Weeds Grow Fast Before Spring

English daisy is a pretty weed.

Vegetables and annuals should be growing well with such pleasantly warming weather. Soon enough and into spring, most should be growing like weeds. Unfortunately though, they are not alone. Undesirable vegetation competes with them for limited resources and space. It is a sadly unavoidable problem, even among the most refined of home gardens.

According to their simplest definition, weeds are undesirable vegetation. Obviously, most of the familiar sorts are annuals or perhaps perennials. However, trees, vines and shrubs can be weeds as well. Silver wattle is an invasive tree which can be difficult to eradicate. English ivy is an invasive vine among many forests. Glossy privet is invasive shrubbery.

With few exceptions, weeds are exotic. In other words, they are not native locally. Native species are generally complaisant within their natural ecosystems. They become weeds only if they become undesirable. For example, native poison oak may grow within home gardens. Native bay trees and some oaks frequently appear where they are undesirable.

Most exotic weeds were not always so undesirable. Some were formerly popular for their ornamental qualities, and then naturalized. These include pampas grass, yellow flag iris, Hottentot fig and periwinkle. Wild mustard likely naturalized from home gardens where it grew as a vegetable. Many naturalized grassy weeds were originally fodder for livestock.

The smaller but prolific weeds are the most problematic for home gardens. They include dandelion, purslane, burclover, various spurges and various thistles. Of course, there are too many to list. They grow and disperse their seed much more efficiently than desirable vegetation. That is how they invade home gardens and become such a prolific nuisance.

That is also why it is so helpful to remove weeds as soon as possible. Their subsequent generations will be less profuse if they disperse less seed now. Besides, they are easier to pull while only beginning to disperse roots within moist soil. They will be more difficult to pull when more established in drying soil later. Weeding may be tedious nonetheless.

Six on Saturday: More Seasonal Bloom

The first is Spanish. The second is Chinese. The rest, including Oregon grape, are native. Only the iris and poppy were actually found growing in the wild, though. It is beginning to look like spring.

1. Lavandula stoechas, Spanish lavender compensates for its absence of floral fragrance with delightful foliar aroma, especially as the weather begins to get warmer after winter.

2. Loropetalum chinense, Chinese fringe flower blooms with these silly rosy pink flowers above lightly bronzed new foliage, which is collectively more colorful than simple bloom.

3. Ribes sanguineum, flowering red currant, although native here, does not grow wild in this particular location. This one was added to one of the landscapes, and is quite happy.

4. Iris fernaldii, Fernald’s iris does grow wild here, and seems to bloom more happily on exposed roadsides than in forests. Perhaps it appreciates the better exposure to sunlight.

5. Mahonia aquifolium, Oregon grape is the Official State Flower of Oregon. It is native, but was likely added to the several landscapes that it inhabits here, like the red currants.

6. Escholzia californica, California poppy is the Official State Flower of California. It can be a bit prolific in some situations, while less prolific where seed are intentionally sown.

Leopard Plant

Leopard plant enjoys shady riparian situations.

Not much can survive in the shade of broad eaves that extend over a northern exposure. With sufficient watering, that is where the leopard plant, Farfugium japonicum, can excel. It is naturally an understory species that prefers the shade of bigger vegetation. If it does not get too dry, it also performs well with full sun exposure. It enjoys organically rich soil.

Leopard plant is a striking foliar plant, but may also bloom for autumn or winter. Its bright yellow daisy flowers are about an inch wide, and bloom in loose trusses. The glossy and evergreen foliage might be foot and a half high. Some cultivars are more compact, while old cultivars may get slightly bigger. Individual leaves are about three to six inches wide.

Popular cultivars of leopard plant are notably diverse. Most are variegated with yellow or white spots, blotches, margins or irregular streaks. Some exhibit wavy, crinkly or convex foliar margins. Yet, the most popular is likely the old fashioned cultivar with simple, deep green foliage. Their subterranean rhizomes migrate, but rather slowly. Too much fertilizer can cause foliar burn or even inhibit bloom.

Microclimates Are Different From Climates

Southern exposures are sunny and warm.

Climates are regionally prevalent patterns of weather. The climate here is a chaparral or Mediterranean climate. It is characterized by warm and arid summers, and mild and rainy winters. Many adjacent climates are similar, even if slightly different. Coastal, alpine and desert climates occur elsewhere in California. Microclimates occur within such climates.

The climates of California are as diverse as the geology that influences them. Mountains and valleys and everything in between develops its distinct climate. Some counties here include more climates than some individual states. Many climate zones are impressively compact. So much diversity with small climate zones is often mistaken for microclimates.

Microclimates are small climates within bigger climates. This is obvious. However, there is no definitive description of how small they are. Climates generally conform to geology, like elevation, latitude and proximity of oceans. Microclimates generally conform to what is on such geology, like forests or pavement. They can fit within compact home gardens.

Roofs and pavement of urban areas absorb and radiate significant heat. Such heat alters associated microclimates. Conversely, urban trees and vegetation might cool associated microclimates. Home gardens that are near freeways may be slightly warmer than those that are not. Well forested neighborhoods are a bit cooler during warm summer weather.

These are large scale examples, though. Microclimates originate within individual home gardens also. Southern exposures are much sunnier and warmer or hotter than northern exposures. Eastern exposures are as sunny as western exposures, but are not as warm. Eaves might shelter vulnerable vegetation from mild frost, but also exclude rain moisture.

Microclimates can change as gardens evolve. Shade trees grow to produce more shade. Taller fences may replace shorter fences. Painting a home a different color changes how it reflects or absorbs sunlight. Awareness of microclimates facilitates selection of species for each particular situation. It also facilitates selection of situations for particular species.
