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: Eliminating Arrow Weed from property in Mohave Valley AZ
Answered by: Barbara Medford

QUESTION:

How do I get rid of Arrowweeds on my property?

ANSWER:

Pluchea sericea (arrowweed) is native to North America and to the entire state of Arizona, according to this USDA Plant Profile, which will make it that much harder to exterminate. If you manage somehow to get it off your property, you will only get seeds from other areas around you, carried in by wind and animals. This Las Pilitas website actually has it for sale, so we guess not everyone is opposed to it. 

Since we could find no very instructive information on this plant, and have no personal experience with it, we suggest you contact the Arizona Cooperative Extension Office for Mohave County.  They can tap into the resources of trained horticulturists familiar with the area and the plant, and make much more informed suggestions than we can.
