Taxus cuspidata 'Thayerae' (Thayerae Spreading Japanese Yew)


Michael's Opinion

A slow growing, broadly spreading Japanese yew cultivar. Its deep green foliage makes it a nice choice for a low lying hedge in any landscape. Its hardiness in harsh climates and pollution tolerance makes it an integral part of most landscapes.
