A nice dark pink or rose colored cultivar of the standard Mimosa tree. From what I can tell they look just like the species in all aspects except the flower color, so please see the description of the tree in that post.
Flowers are much darker pink almost rose colored.
You will see that some good references consider this a botanical form or forma and not a cultivar.
The RHS considers it a forma
The USDA considers it a variety
Cal Poly considers it a 'Cultivar'
