Taxus × hunnewelliana 'Richard Horsey' is a broadly spreading, semi-dwarf selection of Hunnewell hybrid yew with procumbent major branches and ascending secondary branching. Needles are glossy dark green on the adaxial (upper) surfaces and bluish light green abaxially (underneath). Individual needles measure 0.4 to 0.8 inch (10 - 20 mm) long and 0.08 to 0.1 inch (2 - 2.5 mm) broad.
After 10 years of growth, a mature specimen will measure 3 feet (1 m) tall and 5 to 10 feet (1.5 to 3 m) wide, an annual growth rate of 6 to 12 inches (15 - 30 cm).
This species originated as a seedling selected in 1977 by R.F. Doren and distributed by the U.S. National Arboretum, Washington, D.C.
