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: Smarty Plants on Pittosporum
Answered by: Nan Hampton


Need to know if "PITTOSPORUM" (TOBIRA VARIEGATA) will grow in my area of SE OK. I have purchased two of them and the nursery said that they would do great. Just needed an extra opinion. Thank you very much!


Our interest and expertise is native plants of North America, and Variegated Pittosporum (Pittosporum tobira 'Variegata') is an introduced species from Eastern Asia, not a North American native. Information from the University of Connecticut Ecology & Evolutionary Biology Conservatory indicates that it is suitable for USDA Hardiness Zones 9-11. Since you are in USDA Zone 7, you will need to protect it in cold weather.
