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!

Topic: Non-Natives
Title: Non-native impatiens from Charlottesville VA
Answered by: Barbara Medford

QUESTION:

Question about type of impatiens. My Alabama mother grew these and called them touch-me-not. They grow about 2 feet tall and blooms grow UNDER the leaf canopy up the stem. Colors I have are pale pink and fushia. Seed pods are similar to common impatiens only larger. What lighting and other conditions are needed?

ANSWER:

According to this Dave's Garden forum, Impatiens balsamina has the common name of "touch-me-not." According to this USDA Plant Profile, its common name is "spotted snapweed."

This plant is native to Tropical Asia, including India and Myanmar. As such, they do not fall into our realm of expertise, nor appear in our Native Plant Database. The Lady Bird Johnson Wildflower Center is committed to the growth, protection and propagation of plants native not only to North America but to the area in which they are being grown. Here is an article on How to Care for Impatiens which we hope will help you.
