General Culture:
Easily grown in average, medium, well-drained soil in part shade to full shade. Prefers cool, moist, humid conditions. Intolerant of drought and should be watered regularly in prolonged dry spells, particularly when young. Best sited in a location protected from strong winds.
Noteworthy Characteristics:
This Canadian or eastern hemlock cultivar is a globose, dwarf, evergreen conifer which typically grows to 3-4' tall and 4' wide. Needles at the branch tips are silver white, thus giving this shrub the appearance of being covered with snow. Inner needles (to 1/2" long) are dark green with two whitish bands of stomata underneath. Thimble-like, light brown cones to 3/4" long appear on older plants. No part of this plant is poisonous. The poisonous hemlocks (Cicuta maculata and Conium maculatum) are herbaceous perennials in the parsley family.
Problems:
A healthy plant in the proper environment has few problems. Potential disease problems include needle blight (needles turn yellow and die), canker and rust. Potential insect problems include bagworms, borers, leaf miners, saw fly and spider mites. Woolly adelgid (an aphid) is particularly troublesome in the Northeast where it can be fatal. Foliage may scorch in very hot weather, particularly the new growth, white tipped branchlets. Prolonged drought can be fatal.
Uses:
Specimen or group. Foundation planting. Hedge.
