Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: How would chocolate mimosa tree do in Salt Lake City
Answered by: Nan Hampton

QUESTION:

How would the chocolate Mimosa Tree do here in Salt Lake City, zone 5.

ANSWER:

That is a question that I'm afraid Mr. Smarty Plants can't answer for you other than to say we don't recommend planting Albizia julibrissin 'Summer Chocolate' at all.  Not only is this species not native (it originates from Asia), but it is a variety of a species that is considered invasive and is on the Plant Conservation Alliance's Alien Plant Working Group's Least Wanted list.  As a substitute we can offer some Utah native trees that have something of the look of the chocolate mimosa.

Gleditsia triacanthos (honeylocust).  There are thornless varieties and they are hardy to zone 4.

Cercis orbiculata (California redbud.  Here is more information from the US Forest service.

Purshia mexicana (Mexican cliffrose).  Here is more information from Desert USA.

Robinia neomexicana (New Mexico locust)

Robinia pseudoacacia (black locust)


Gleditsia triacanthos
