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: Is Viburnum dilatatum 'Henneke' (Cardinal Candy) toxic to horses?
Answered by: Nan Hampton

QUESTION:

Is Viburnum-Cardinal Candy/Viburnum dilatatum 'Henneke' reported to be toxic or non-toxic to horses?

ANSWER:

First of all, for the record, Viburnum dilatatum 'Henneke' (Cardinal candy) is native to Southeast Asia, not North America.  The ASPCA's Toxic and Non-Toxic Plants – Horses lists one Viburnum species, Viburnum lentago (Nannyberry), as a non-toxic plant.  No other Viburnum species are listed there as either toxic or non-toxic.

None of the databases below list any Viburnum species as being toxic.
