Bristlecone Pine
Discovery Japanese Elm

Bristlecone Pine is a small to medium evergreen with an irregular habit and contorted branches.

This extremely long-lived tree is relatively low maintenance and drought-tolerant.

It is known for its deep green to blue-green needles flecked with white resin, and its thin, scaly, grey-brown bark. Because it is extremely slow-growing, Bristlecone Pine is well suited to smaller properties.

Discovery Japanese Elm is great for anyone who doesn't have a lot of time to maintain their trees as it doesn't drop many seeds. It has beautiful dark green foliage and is resistant to Dutch Elm Disease. This elm is similar in shape to the American Elm but is roughly 30% smaller. Instead of having an irregular and broad-shaped crown as other Japanese Elms do, the Discovery Japenses Elm has symmetrical branching, an upright growth form, and develops a classic vase-like crown.
