Here on the West Coast, privets had traditionally functioned like hollies had in the East. They are conducive to shearing into the big formal hedges that were popular during the Victorian period. Since then, as gardening space became more limited, the common glossy privet became less popular than the more compact and complaisant waxleaf privet, Ligustrum japonicum ‘Texanum’.
Since it does not get much higher than ten feet, and typically stays less than eight feet tall, waxleaf privet is proportionate to urban gardening. As a formal hedge, it can be shorn to stay less than two feet from front to back, although taller hedges look better if allowed to get bulkier. As an unshorn informal screen, it should not get much broader than six feet, with an appealingly billowy form.
Foliage is evergreen and remarkably glossy, sort of like that of holly, but without the prickles. Regularly shorn hedges should not bloom, but might produce a few trusses of tiny white flowers inside of the shorn surfaces. In sunny situations, unshorn glossy privet blooms profusely enough to be mildly fragrant in spring. Bloom sometimes produces floppy clusters of tiny but messy black berries.
A flower that is so prominent in American culture should have a more appealing name than black-eyed Susan. Even the Latin name, Rudbeckia hirta, sounds bad. Is Becky really so rude? Did she hirt Susan? Well, black-eyed Susan is good enough to be the state flower of Maryland, and is one of the most popular of flowers for prairie style gardens of the Midwest. After all, it naturally grows wild in every state east of Colorado. Here in the West, it is a light-duty perennial that is more often grown as an annual. As a cut flower, it can last more than a week.
Within its natural range on the West Coast between the southern extremity of Alaska and the southern extremity of California, Western sword fern, Polystichum munitum, is the most common of the native ferns. A few disjunctive wild colonies live as far inland as the Black Hills of South Dakota. Yet, with few exceptions, Western sword fern is difficult to cultivate outside of the natural range.
If you’re going to San Francisco, be sure to wear some flowers in your hair. In the 1960s and 1970s, such accessorizing with Paris daisy, Argyranthemum frutescens (which was at the time, Chrysanthemum frutescens), was a fad. The white flowers with yellow centers were about two or three inches wide. Modern cultivars have smaller flowers that might be light pink or pastel yellow.
Some of us might remember Delta maidenhair fern, Adiantum raddianum, as a houseplant that was popular for terrariums in the 1970s and into the 1980s. Although quite happy in terrariums, it eventually gets big enough to crowd other plants in such tight spaces. It prefers to be potted on a porch, or in a regularly watered and sheltered spot in the garden. It tolerates quite a bit of shade.
The weather here is excellent for growing all sorts of fruits and vegetables, but is not exactly ideal for bell peppers. Cool nights between warm days are comfortable for us, but limit production of even the healthiest and most robust of plants. Although they like warm nights, the fruit can be sensitive to hot days, and can even get scalded. Bell pepper plants like rich soil and regular watering.
Of all the aggressively invasive exotic species on the West Coast, Himalayan blackberry, Rubus armeniacus, could be the nastiest! It seems to be impossible to kill. It forms dense thickets of wickedly thorny canes that develop roots where they touch the ground. Even if canes are cut to the ground, and the roots are pulled out, new plants regenerate quickly from remaining bits of roots.
It may not look too nasty, but barberry, Berberis thunbergii, is the sort of small hedge that one goes through only once. It does not have big strong branches to hold anyone back. In fact, the limber branches are quite twiggy. The tiny spines are not impressive either, and might go unnoticed by cursory observation. Yet, they are sharp enough and plentiful enough to make quite an impression!
From formerly dormant bulbs just below where their foliage shriveled in the warmth of last spring, the naked brown floral stalks of naked lady, Amaryllis belladonna, grow fast to about two feet tall. They bloom suddenly with a few or several garish pink lily flowers about three inches long. They are sneaky about it too. Without foliage, and prior to flashy bloom, the bare stalks are easy to miss.
It is not easy to get a pretty picture of rhubarb, Rheum rhabarbarum. The big and sometimes flabby leaves are only impressive to those who know about the succulent petioles (leaf stalks) below. The petioles do not look like much either, until they are cooked into pies or garnet colored preserves. Shabby stalks of tiny flowers rarely bloom, and should get cut out to favor more foliar growth.
