Sidney Waxman's Conifers
Sidney Waxman searched high and low for witches' brooms to propagate as dwarf conifers.
These beds feature many plants introduced by Sidney Waxman (1923-2005), a longtime professor of plant science at the University of Connecticut. Dr. Waxman discovered that from witches' brooms, clumps of unusually dense growth in otherwise normal treas produce a high percentage dwarf trees. He hunted for witches' brooms throughout New England, sometimes using a rifle to shoot Bower cones from high branches. Then he planted the seeds and observed the resulting seedlings to find unusual plants to clone and introduce as cultivars. Waxman was patient, in some cases waiting more than 20 years before deciding whether a plant was worthy of naming and propagating for use in gardens.
In his 40-year career, Waxman planted more than 200,000 seedlings and introduced 40 conifer cultivars, including many dwarf and miniature varieties of eastern white pine (Pinus strobus). His introductions are renowned for their beauty and resilience.
