Abstract
A Japanese Yew plant has been discovered and asexually reproduced which is resistant to "winter burn" from severe winter weather in cold extremes of temperate zone climates. The plant has flat needles, shiny green on top and paler green below, the terminal ends having single sharp points. The bark of the stems is reddish brown and glossy. The buds are ovoid oblong, green in the spring and summer, and change to brown in the fall. The foliage is dense and tends to spread.

I claim as my invention: 1. The new and distinct variety of "Taxus cuspidata Spring Green" plant as described and illustrated in the foregoing specification characterized particularly by hardy resistance to stunting of growth and browning of foliage caused by winter burn.
