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!

Answered by: Jimmy Mills


Are chilean Mesquite tree pods poisonous to dogs?


When we get questions about plants toxic to animals, there are several databases listed below that we regularly consult.

Toxic Plants of Texas

Poisonous Plants of North Carolina

Cornell University Plants Poisonous to Livestock

University of Pennsylvania Poisonous Plants

Canadian Poisonous Plants Information System

The ASPCA has a list specific to dogs; Toxic and Non-toxic Plant List—Dogs.

Checking these databases reveals no record of the genus Prosopis being toxic to dogs. The Chilean mesquite, Prosopis chilensis, however is a non-native species, so it may not be listed in the sources above. On the other hand, mesquite beans have been harvested and ground for flour for human consumption for years. In addition, tucked away in this article "Mesquite Trees in Arizona" is the factoid that in the late summer and fall, 80% of a coyote's diet  may consist of mesquite beans.

From all of this, I would conclude that Chilean mesquite beans are probably not toxic to dogs.
