Description

This variety of pine is both rigid and twisted, reaching 20' tall and 10' wide. It has an irregular shape, and the short, contorted branches eventually produce a canopy-shaped tree. Bright green needles are 4" long. New foliage, called candles, are white colored. Cones are oval shaped and brown, about 3" long. This is a great tree for an outdoor Christmas tree or for bonsai. It needs full sun and a moderate amount of water. This plant is fire-prone! Please use caution when planting near your home.

 

This plant is on the City of Ashland’s Prohibited Plant List and should only be planted if it is at least 30 feet away from any structure. Prohibited Flammable Plants List Questions? Contact Firewise staff at 541-482-2770.
