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: Are blue spruce (Picea pungens) poisonous?
Answered by: Nan Hampton


Are blue spruce trees poisonous at all? Thank you.


Mr. Smarty Plants would say that Picea pungens (blue spruce) is not poisonous since it does not appear on any of the following toxic plant databases:

Canadian Poisonous Plants Information System

Poisonous Plants of North Carolina

Cornell University's Plants Poisonous to Livestock

University of Pennsylvania's Poisonous Plants

University of California–Davis Toxic Plants
