detailed seed-starting info below

Endangered native tree. I grew a single specimen from seed years ago, which lived in our nursery area for a long time (where I was never quite sure of its identity). After I finally moved it to a more permanent location in our back yard, it bloomed,only to reveal it was a Maackia amurensis instead. So despite several attempts to grow this species from seed, I have yet to do so successfully. To remind myself how tall it can get, I keep the photo on this page on hand of a huge specimen I encountered in Morris Arboretum in spring 2010.

This plant used to grow in our garden, but it slipped away...

Seed for this plant is included on my seed trade list

Seed-starting details for this plant

  1. JLH '01 sd. Nicked, soaked, pot 70F (100%G, 3-6d). Not all survived)
  2. Same seed as above, lightly sandpapered. Baggy 70F (100%G, 4-10d)
  3. Seed from JLH '14 order (age unknown). Sandpapered, soaked, baggy 70F (25%G, 8d). Roots emerged, but in only one case did leaves develop. I suspect that seed was nearing or past its use-by date
