ONLY AVAILABLE BY CONTRACT GROW
Black Locust is an attractive tree. Its distinctive leaves are made of about a dozen bright green leaflets. It also notable for its fragrant white flowers, which smell of citrus.
Black Locust can grow in many situations, but prefers dry areas with lots of sun. It is robust and is an excellent choice for establishing shade in dry, open areas.
Important note: Much of the Black Locust is toxic to humans and livestock, including seeds, bark, and leaves.
Siberian Elm is a small to medium-sized deciduous tree. It has a similar form to American Elm, but smaller, with a more pyramidal habit and shorter lifespan. It is also more resistant to Dutch Elm disease and is very salt tolerant.
Siberian Elm was grown as shelterbelts in the prairies after the Dustbowl disasters, where its rapid growth and tolerance for drought and cold initially made it a great success. It is an excellent shade tree.
Note: Due to it's increasingly controversial reputation for being invasive in warmer climates, we are no longer planning to grow this species for retail purchase on a regular basis.
