Unlike the species, which blooms in July here in Boston Z6a, this cultivar blooms in late August and September. It was selected and named by the Arnold Arboretum for the pink color of its (ornamental) immature seed capsules, which form in October and November. This is an aggressive self-sower, and it's a high-maintenance tree if you take into account the time required to remove unwanted seedlings.

And I wonder if this isn't in the next generation of plants we find out is invasive of natural habitat.

Of all the trees with what I'd consider a showy flower display, this is the latest to bloom.

I've had this tree for about 10 years, it's lovely. My issue, 100's of seed pods creating small trees everywhere in the lawn! Wish I never planted it! Fast germination.

I have one of these trees in my back yard. It gets about 6 hours of afternoon sun per day and is about 15 feet tall. My problem is it has never had one bloom or seed pod on it ever. It is a very healthy vigorous tree but I really would like it to bloom. Any suggestions ???

Thanks

Blooms 2 months later than Golden Raintree and has pink-red seedpods instead of brown. It has kind of a goofy shape when it's young but develops a lot of character as it ages. Low maintenance, drought tolerant and has showy flowers in August. The new growth is very colorful too.
