Leadplant (Amorpha canescens) has a shrub forming habit and can grow up to 3 feet tall. Leadplant is native to the central parts of Canada and the U.S. and is hardy in zones 3-8. It is tolerant to a range of soil types and is happiest in full sun. Deep roots allow for drought tolerance and the ability to survive fires. Leadplant is also a member of the pea family, allowing it to fix Nitrogen, making it available to other neighbouring plants. Note, this long lived perennial may take up to 4 years to reach maturity and flower.
Cold, moist stratification required. Mix seeds with moist substrate (vermiculite, perlite or moss) and place in a plastic bag and refrigerate for 6-8 weeks. Sow seed at 1/8 inch depth. Do not let seedling dry out while it is establishing.
