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: Information about invasive Paulownia tree
Answered by: Nan Hampton
QUESTION:
What genus and species and family is this Royal Paulownia tree I hear about? Is it Elm? Linden? Dogwood? Is it a weed? thank youANSWER:
Paulownia tomentosa (royal princess tree), a native of China, is a member of the Family Scrophulariaceae (Figwort Family). There are no trees native to North America that are in this family—elm is in the Family Ulmaceae, linden is in the Family Tiliaceae, and dogwood is in the Family Cornaceae. A few familiar North American plants in the Family Scrophulariaceae are: the paintbrushes (Genus Castilleja), the monkey-flowers (Genus Mimulus) and the louseworts (Genus Pedicularis).Mr. Smarty Plants certainly considers it a weed! Please note what Texas Invasives says about it:
"Princess tree is an agressive ornamental tree that grows rapidly in disturbed natural areas including forests, streambanks, and steep rocky slopes."
It is also is listed in the Invasive Plant Atlas of New England, in the Plant Conservation Alliance's Alien Working Group Least Wanted list and the Federal and State Noxious Weeds list.
If you are considering planting a royal paulownia tree, we urge you to consider these native alternatives:
Amelanchier arborea (common serviceberry)
Cercis canadensis (eastern redbud)
Cornus florida (flowering dogwood)
Lindera benzoin (northern spicebush)
