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.

Six on Saturday: New Leaf

Warming spring weather is stimulating new growth among vegetation that was dormant or shabby through this winter.

1. Rosa spp., rose started growing even before the weather became warmer. It is good to see that squirrels are not eating the new growth. I do not know what cultivar this one is.

2. Hydrangea macrophylla, hydrangea, which is also unidentified, also started growing while the weather was still cool and rainy. It is now settling in after bare root relocation.

3. Nephrolepis cordifolia, sword fern, like many ferns, is beginning to replace old foliage with new foliage. It grew too large for its pot years ago, but somehow continues to grow.

4. Clivia miniata, Kaffir lily has been maturing slowly for more than a year, but is finally providing a pup. It is variegated with yellow stripes, but I do not know what cultivar it is.

5. Brugmansia X cubensis ‘Charles Grimaldi’ angel’s trumpet is producing a new flower as readily as it produces new foliage. It should be no surprise. it is rarely without bloom.

6. Musa acuminata X balbisiana ‘Golden Rhino Horn’ banana starts to produce its new foliage about the time we consider taking it out of the landscape because it is so shabby.

Tomato

Tomatoes epitomize the warm season vegetables.

Like most warm season vegetables, tomatoes, Solanum lycopersicum, are actually fruits. They contain seed, whereas actual vegetables are vegetative plant parts that lack seed. Although mostly red, some are orange, yellow, green, pink, brown, purple or pallid white. Some are smaller than small grapes, while ‘Beefsteak’ may grow wider than five inches.

For home gardens, the most popular varieties of tomato are indeterminate. They produce their fruit sporadically throughout their season, on lanky irregular stems. They are neater with the support of tomato cages or stakes. Determinate varieties are shrubbier and more productive, but only for a brief season. They are quite conducive to succession planting.

It is still a bit too early for small tomato plants to go into their gardens. However, seed can start inside or in a greenhouse now. It is possible to sow seed directly into a garden later, but they are vulnerable to mollusks. Nurseries can stock several varieties of tomatoes as small plants. Countless more varieties are available from mail order or online purchases. Many heirloom varieties truly are strange and unique.

Warm Season Vegetables Are Next

Summer squash grows easiest from seed.

Warm season annuals know what time it is. Although it is still too early for many to move directly into gardens, a few already are. A few can start from seed, either in greenhouses or directly in their gardens. Eventually, as the weather warms, they all can live outside for the summer. Warm season vegetables, or summer vegetables, are in the same situation.

After all, almost all warm season vegetables perform as annuals. The weather is still too cool for seedlings to go out into their gardens. However, it is time to start some vegetable plants from seed. Some should start inside or in a greenhouse. Others might start directly in their gardens. The weather should be warm enough for them by the time they develop.

Seed for most root vegetables can go directly into their gardens now. Root vegetables do not recover from transplanting easily, so prefer direct sowing. Transplanted seedlings are susceptible to root disfigurement. Corn, squash and beans prefer direct sowing also, but should wait for warmer weather. Seedlings grow faster than the weather becomes warm.

Tomato and pepper plants prefer to go into the garden later as seedlings or small plants. Such small plants will become available from nurseries as they become more seasonal. Alternatively, they can start to grow from seed inside or in a greenhouse now. Their fresh seedlings should be ready for their garden as the weather warms. Scheduling is crucial.

The advantages to seed are that it is less expensive and more diverse than small plants. Packets of seed cost about as much as six packs of small plants, but contain many seed. Nurseries stock only a few varieties of each type of vegetable plant. However, they stock a few more varieties of seed for the same type of vegetables. Many are available online.

Cucumber, eggplant and melon can grow either from small plants or directly sown seed. A single small plant may be more practical for melon because only one plant is sufficient. However, if several cucumber plants are preferable, seed may be more practical. If seed are preferable, they can start soon. Small plants might wait a bit longer after the last frost.
