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: Non-native fountain grass for Edwardsburg MI
Answered by: Barbara Medford

QUESTION:

I purchased a purple fountain grass by a vendor @ the Plymouth, IN blueberry festival. He told me that it is a perennial. I live in Edwardsburg, MI and I keep reading that in my area, they are considered annuals. What is correct?? I love this grass and would love to have it back every year without having to re-plant.

ANSWER:

The Lady Bird Johnson Wildflower Center is committed to the care, protection and propagation of plants native not only to North America but to the area in which it is being grown. Pennisetum setaceum, fountain grass, is native to Africa and Saudi Arabia, among others. The word "Purple" attached to the plant you bought no doubt was a vendor-selected description. Not only is this plant out of our area of expertise, but it is considered a harmful invasive in the areas in which it can be grown, none of which are as far north as Michigan. Read this Plant Conservation Alliance's Alien Plant Working Group 'Least Wanted' article on Fountain Grass.

In our Native Plant Database, we have found seven grasses that are similarly attractive to the fountain grass, but are all perennial and all native to Michigan. Follow the links to the page on each grass for more information.
