General Description

A compact, conical dwarf shrub, the blue-green needles of Deborah Waxman dwarf tamarack turn coppery gold in autumn. Native to much of Canada and the extreme northern United States, this variety was selected by Sid Waxman of the University of Connecticut. It is a very slow growing, dwarf, deciduous cone-bearing shrub with dense branches and needled foliage.

The needles are bright blue-green, short, three-sided and arranged densely in spiral clusters atop short stubby spurs. The branchlets are congested, making the small pyramid-like shrub dense. With age, the male and female cones may appear on the branchlets in late spring, and the female cones that develop after pollination are quite small, egg-shaped, tan, and remain through the winter and following spring. The return of cool nights in late summer will find the foliage turning yellow and gold.

Provide a full sun exposure for the Deborah Waxman dwarf tamarack and place it in a moist, well-draining, acidic soil. It is tolerant of wet, boggy soils as well. Often difficult to locate in the nursery trade, it will be encountered only in regions with very cold winters and cool summers. It resents shade, root disturbance, drought and pollution and therefore is best used as an undisturbed specimen in the mixed border or conifer garden.
