A mature persimmon tree, Diospyros kaki, is often too much of a good thing. The fruit is both big and abundant as it ripens this time of year. Much of the fruit in taller trees is out of reach. Nearly ripened but somewhat firm fruit can be picked and shared with neighbors for a while, but must be picked immediately once completely ripe. Otherwise, it falls and makes a squishy mess that can not be raked up! Nearly ripe fruit ripens easily off the tree. Individual fruits only need to be spread out in a single layer to limit molding.
‘Fuyu’ is probably the most popular variety because the ripe fruit can be eaten while still firm, or after it has gotten soft. ‘Hachiya’ produces the largest fruit, sometimes bigger than a softball; but the fruit is too astringent to eat until completely ripe. It is actually best after it is so overly ripe that it is too squishy to handle. Persimmon fruits are very bright orange. ‘Hachiya’ fruit can be slightly reddish. The foliage gets just as colorful. Typically, the foliage colors first, and then falls to reveal the fruit. This year, the fruit seems to be coloring first.
Not to be confused with the Canadian rock band from the 1970s, this rush, Juncus patens, is native to riparian areas between western Washington and San Diego County. It is also known as the common rush because it is, obviously, the most common species of the genus on the West Coast. It is only occasionally planted intentionally, but more often sneaks into well irrigated landscapes.
Out in rural chaparral regions, where water is scarce, the big and bold California sycamore, Platanus racemosa, somehow seems to find the spots where groundwater is not too far below the surface of the soil. It is technically a riparian tree, that is just as comfortable competing with cottonwoods and willows along forested rivers and floodplains. It eventually get too big and messy for refined urban gardens, but is somewhat popular nonetheless.
Like a flower girl scatters rose petals ahead of a wedding procession, European white birch, Betula pendula, tosses its small deltoid leaves soon after turning soft yellow with autumn chill. Color may not last long on the trees, but becomes a delightful mess for those who appreciate such assets. The primary allure though, is the slender strikingly white trunks, accented with black furrowing.
It is unfortunate that, like Easter lilies and poinsettias, most kalanches, Kalanchoe blossfeldiana, are enjoyed while actively blooming, and then discarded as their blooms fade. It is so easy to simply snip out the deteriorating flowers, and grow the small perennials plants for their appealing succulent foliage until they bloom again. They do not get much more than half a foot tall, so can stay in small pots indefinitely. They seem to prefer the porosity of clay pots. Because they can rot, they should be watered when the surface of the soil seems to be getting dry, and their drainage saucers should not be allowed to hold water too long. Kalanchoes like bright but indirect sunlight. They can be acclimated to direct sun exposure, but might seem to be somewhat stunted. If brought in before frost, they can be happy out on a patio. The clustered small flowers can be white, pink, red or bright or pastel shades of orange or yellow.
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.
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!
