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: Sunflowers for Terrell, Texas
Answered by: Nan Hampton

QUESTION:

What sunflowers grow best in Terrell, Tx?

ANSWER:

Helianthus hirsutus (Hairy sunflower) is the only plant with the common name "sunflower" that grows in Kaufman County.  Plants in the Genus Helianthus are those that are generally known as "sunflowers".  You can see them in Kaufman County on the USDA Plants Database distribution map.

There are several species of Helianthus, however, that occur in counties adjacent to Kaufman County that should grow well in Kaufman County also.

Helianthus angustifolius (Swamp sunflower) grows in Henderson County.

Helianthus annuus (Common sunflower) grows in Dallas, Rockwall and Hunt Counties.

Helianthus maximiliani (Maximilian sunflower) grows in Dallas, Rockwall and Hunt Counties.
