American Basswood (Heterophylla)

The American Basswood (Heterophylla) is generally described as a perennial tree. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The greatest bloom is usually observed in the early summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The American Basswood (Heterophylla) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical American Basswood (Heterophylla) will reach up to 90 feet high, with a maximum height at 20 years of 50 feet.

The American Basswood (Heterophylla) generally appears in field collections and doesn't tend to be commercially available. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -8°F. has low tolerance to drought and restricted water conditions.
