Ah, something vintage! Remember Hollywood juniper, Juniperus chinensis ‘Kaizuka’ (or ‘Torulosa’) flanking big two-car garage doors of mid century modern homes? Those that are still around after half a century are big and strikingly sculptural, like miniature Monterey cypress for home gardens. They get about fifteen feet tall and ten feet wide, but have potential to get significantly larger.
Hollywood juniper is an old classic that is still reasonably available in some nurseries. Their densely foliated stems twist and turn picturesquely upward, typically leaning one way or another toward sunlight or away from prevailing wind. Some say they look like frozen green flames. Their gnarly trunks and flaking bark can be exposed as they grow tall enough for low growth to be pruned away.
Because of their very irregular branch structure, Hollywood juniper is more adaptable to free-formed pruning than the presently trendy junipers with strictly upright or conical form. They must never be shorn, but do not mind if obtrusive limbs get pruned back to the main trunks. Therefore, they are actually more adaptable to smaller modern gardens than some modern cultivars of juniper are.
It is almost never planted in home gardens, but the native red willow, Salix laevigata, has a sneaky way of getting where it wants to be. The minute seeds go wherever the wind blows them. Because it is a riparian tree, red willow prefers well watered spots. If not detected and pulled up in the first year, it can grow rather aggressively, and overwhelm more desirable plants, although the somewhat sparse canopy makes only moderate shade.
The ‘X’ preceding its Latin name ‘X Cupressocyparis leylanii‘ designates Leyland cypress as a hybrid of two distinct genera, namely Monterey cypress and Nootka cypress. (Those who consider the parents to be two species of the same genus know Leyland cypress as Cupressus X leylandii.) The many cultivars combine desirable qualities of both parents, but also innate weaknesses.
As the colorful deciduous trees go bare, the evergreen trees get more attention. A weeping white spruce, Picea glauca ‘Pendula’, really stands out. It grows slowly to only about fifteen feet tall and maybe five feet wide, so does not need as much space as a typical spruce tree. What makes it so distinctive is the weirdly pendulous stems that hang limply from a strictly vertical trunk. It is hard to believe that it is only a different variety of the same species as the dwarf Alberta spruce, which is very short, dense and symmetrically conical, with stout little stems. The foliage of weeping white spruce is lighter green than that of most other spruces, but is not as blue as that of blue spruce. The short and stiff needles are rather prickly to handle.
Of all the Official State Trees, the coastal redwood, Sequoia sempervirens, of California is the grandest. Seriously, it is the tallest tree in the World, so it really ‘is’ the grandest! The tallest is 380 feet tall! Although the related giant redwood of the Sierra Nevada develops bigger trunks, the bulkiest coastal redwoods are thirty feet wide at the base! The oldest are more than 2,000 years old!
Mild autumns and arid summers keep chrysanthemums on a different schedule here than in most other regions. They can get planted in spring to grow through summer and bloom through autumn; but because they can take a bit of work, they are more often planted while blooming in autumn. Although commonly grown as autumn annuals, they are perennials that can regenerate next spring, grow through summer, and bloom even better the following autumn.
It really would be nice to be able to transform a pumpkin into a chauffeured coach to ride to the ball, just by waving a magic wand over it. A Buick would be even more excellent! Over the years, as the variety of new Buicks has diminished to not much more than a few SUVs that are scarcely more stylish than pumpkins, the variety of pumpkins has grown crazily. Form is not following function.
The recent unseasonably warm weather was no problem for any remaining moss rose, Portulaca grandiflora. They usually start to look rather tired as the weather gets cooler this time of year, and eventually succumb to the first frost. Where allowed to do so, they can regenerate next year from seed. I like to collect their seed during the summer or autumn so that I can sow them after the last frost of the following winter. Through spring and summer, I find that additional plants are easy to grow from cuttings.
It is easy to mistake various cultivars of Dyckia for diminutive relatives of Agave or Yucca. They form stout rosettes of rigid leaves with wickedly sharp terminal spines. Their comparably nasty but incurved marginal teeth resemble those of most species of Agave, but are generally more abundant. Surprisingly though, Dyckia are instead related to bromeliads. They just happen to be xeric.
Angelonia is one of those warm season annuals that can actually survive through winter as a pernnial to bloom again next spring. It may even want to continue to bloom untill frost. The flowers can be blue, purple, red, pink or white, and look something like small snapdragon flowers. Most have spots or stripes of an alternate color or two in their throats. Some modern varieties have fragrant flowers. Plants can get a foot or two tall, and almost as wide. In sheltered spots, angelonia can be cut back as soon as it starts to look tired in autumn. Exposed plants might be happier if cut back significantly later, as winter ends. Old growth may be unsightly for a while, but can protect interior stems and roots from frost. Besides, pruning stimulates new growth that will be more susceptible to subsequent frost.
