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.

Title: Best performing species on green roofs
Answered by: Dr. Mark Simmons and Joe Marcus

QUESTION:

Hello, I am a graduate student in Nova Scotia Canada studying native plant communities on green roofs. I have been reading about the native planted green roof at the Lady Bird Johnson Wildflower Center and am interested to know how well the native plants performed and survived in your region of the world. Thank you, and great website!

ANSWER:

We wish we could give you a more definitive answer, but it's still a bit too early.  Right now we are still analyzing the data. There is considerable variation both among plant types and among roof types (i.e. a plant that does well on one roof type may do poorly on another). Although there are many exceptions, overall, as a guide, the grasses seem to do the best. The list can be found at http://www.wildflower.org/collections/collection.php?collection=greenroof_species
