‘Red Star’ Atlantic Whitecedar

60106Is it red or white? Actually, it is neither. ‘Whitecedar’ is the common name for Chamaecyparis thyoides, which is a formidable coastal conifer from Maine to Mississippi. ‘Red Star’ is a much smaller garden variety. Its finely textured foliage is bluish green when it first emerges in spring, and can turn slightly purplish or bronzed gray if it gets cold enough in winter, but never turns red.

In more humid climates, ‘Red Star’ Atlantic whitecedar can eventually reach second story eaves, and can get half as broad. It rarely gets half as large locally, and can take quite a few years to do so. The slightly aromatic evergreen growth is densely conical, almost like a lumpy dwarf Alberta Spruce with an upwardly rounded underside. It can be a bit more sculptural if partially shaded.

Even without pruning, ‘Red Star’ Atlantic whitecedar is symmetrical enough for formal landscapes. Alternatively, it can add a bit of formality to relaxed landscapes. Although it is slow to provide privacy, it works nicely as an unshorn hedge. If somewhat crowded in a row, it grows taller faster. Shorn hedges lack natural form, but can recover their natural texture between shearing.


Deodar Cedar

81205Some of us may remember deodar cedar, Cedrus deodara, from the opening scene of the Andy Griffith Show. They were in the background as Andy Taylor and his son Opie skipped stones on Myers Lake near Mayberry in North Carolina. Those well established and naturalized trees and the pond are actually in Franklin Canyon Park in the Santa Monica Mountains above Beverly Hills.

If only it did not get big enough to shade most of a compact home garden, deodar cedar would be better than most other evergreen coniferous trees used in California landscapes. It enjoys the warmth and sunshine here, and does not require any more water than what most regions that are not desert get from rain. It eventually gets fifty feet tall and thirty feet wide, and might get bigger.

The glaucous grayish needle leaves are about an inch or two long, and are arranged either in tight terminal clusters on the tips of short and stout stems, or singly on longer and pendulous shoots. Ideally, trees develop conical canopies with horizontal limbs that droop at the tips. Some trees develop a few main trunks down low, or big structurally deficient limbs that curve irregularly upward.

My First Tree

71108Calocedrus decurrens. Incense cedar. The first tree that I ever planted was a small incense cedar, like the tree in the picture here. Of course, it was not this big when I planted it.

It came from my maternal grandparents’ cabin near Pioneer, in the foothills of the Sierra Nevada. It was a wild seedling that might have been pulled up because it was where the cabin was to be built. My grandmother planted it into a small wooden planter in the backyard. Once it recovered and started to grow, she gave it to my parents, who had me plant it on a small hill in the back yard. Although not native to the Santa Clara Valley, it did well, and grew tall and lean. I tend to compare all incense cedars to my first tree.

Almost all are older and bigger, with plump trunks. I can guess from their age that most were planted during the Victorian Period. Quite a few were planted half a century later, during the 1950s, when Monterey pine and Monterey cypress were too commonly planted. Not many incense cedars are young. It is as if they had been available in nurseries until the early 1970s, and were not grown much after that. I planted a few in Scott’s Valley back in the 1990s, on the southern margin of what is now Sky Park, but only because my colleague happened to grow them.

Because it was less expensive to transport ‘relatively’ local lumber than to import Eastern red cedar lumber from the East, incense cedar provided the veneer for closets of old homes here, as well as cedar chests. Small groves of incense cedar were grown in the Santa Cruz Mountains as a local source of cedar wood. Now that cedar closets and chests are no loner necessary to repel moths from woolens and furs, the naturalized groves are abandoned, and now grow wild. I know that they are technically not locally native, but I still like to see a few of them around. They look so much like my first tree.

Dwarf Alberta Spruce

81031It is so tempting to dress up a densely conical dwarf Alberta spruce, Picea glauca ‘Conica’, as a garden gnome for Halloween. They are so symmetrical that they seem to have been shorn that way. They are too small to be classified as trees, but are not as shrubby as most shrubbery either. Their practicality is rather limited to formal situations where their strict symmetry is desirable.

Dwarf Alberta spruce is very different from the straight (not dwarf) species that can get to almost fifty feet tall. It instead grows very slowly, and stays quite small, although it can eventually reach downstairs eaves. The finely textured evergreen foliage is soft but slightly bristly. The tiny individual needles are only about half an inch long. The aroma of crushed foliage might be objectionable.

Dwarf Alberta spruce is popularly grown as a potted Christmas tree, and happens to be one of the few coniferous plants that can stay potted long enough to functions as such for a few years. In the ground, it wants rich but well drained soil. It can rot if the soil stays too damp. Red spider mite can be a potential problem. Although it likes full sun exposure, it can get roasted in hot situations.

Plan Ahead For Coniferous Evergreens

81031thumbWe all know what autumn is for. Planting, of course. Yes, it is a recurring theme; but there are so many different things to plant. Dormant bulbs need to get into the ground before cool and rainy winter weather. Deciduous plants that should be planted while dormant prefer an early start if planted as soon as they defoliate in autumn. Believe it or not, most evergreen plants are no different.

Evergreen plants do not experience the degree of dormancy that defoliated deciduous plants do, but they too are significantly less active during autumn and winter than they are during warmer weather. Therefore, if possible, they should also be planted in autumn, so that they can begin to slowly disperse roots through winter, to be ready to resume growth as weather warms next spring.

All planting should be planned. This is more important for trees, big shrubbery and other plants that are difficult to relocate once they have dispersed their roots. Some broadleaf evergreens that get bigger than expected can be pruned into submission. However, most coniferous evergreens are notoriously difficult to contain if they get too big for the situations into which they get planted.

‘Coniferous’ plants are those that produce cones. Cypress, pine, fir, spruce, cedar and redwood are the more familiar coniferous trees. Most coniferous trees, except for most of the various cypress, have excurrent branch structure, with lateral limbs extending from a central trunk. They can not be pruned down without disfiguring their central trunks. Lateral limbs can be disfigured if pruned back. Such trees should therefore be planted where they can grow unobstructed to mature size.

Juniper and arborvitae are some of the more familiar of coniferous shrubbery. They can be shorn even into formal hedges, but only if shorn very regularly. Their dense foliage shades out interior foliage. If they get too big for the respective situations, they can not be pruned back into submission without exposing their bare interiors. Once exposed, bare interior stems may never recover.
