Calocedrus decurrens (California incense cedar)

This hemlock cultivar makes a very beautiful specimen, slowly forming a 10- to 15-foot-tall and 30-foot-wide, multi-layered mound of greenery. Its horizontally speading branches are covered with smaller weeping branches clothed in short, dark green needles. It looks great growing over a rock wall, in a rock garden, or by water. Its size may be controlled by regular clipping.

This North American native grows to 70 feet tall, with a broadly pyramidal outline. It has deeply furrowed bark, small, oval cones, and slightly drooping branchlets with finely textured needles. It is suitable to a wide variety of uses, such as hedging or screening, and group or specimen plantings. It has given rise to a number of notable cultivars.

This glorious conifer constitutes the sole member of both its genus and plant family. It is without a peer in its beauty; on a mature specimen, its rich needles compose a sculpture of form, texture, and color that is unrivaled. The foliage develops a bronzy tint in winter. While it often grows to 30 feet in cultivation and 90 feet in the wild, its slow-growing nature inspires patience.

Sourwood, the lone species of the genus, is found in woodlands and along streams of eastern North America. This plant (named for the sour taste of its leaves) forms a pyramidal tree to 30 feet tall, with canoe-shaped, glossy leaves that turn vivid maroon, yellow, or purple in autumn. In late summer, its delicate panicles of fragrant, urn-shaped flowers spray forward, decorating the tree in white. The blossoms, which resemble lily-of-the-valley, are followed by yellowish seed capsules that turn brown and persist into winter. It makes an outstanding specimen both for a prominent position and also for a naturalized setting.
