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: Reseeding with Gulf cordgrass, Spartina spartinae
Answered by: Damon Waitt


Are the seeds of Spartina spartinae sterile? If not, when is the best time to harvest for replanting? We are involved in the restoration of the Bahia Grande section of the Laguna Atascosa National Wildlife Refuge.


Apparently not. According to the USDA Plants Factsheet for Spartina spartinae (gulf cordgrass), restoration of coastal sites by seeding is possible although gulf cordgrass is best propagated vegetatively. Currently the Kika de la Garza PMC is evaluating the seed potential of gulf cordgrass. Two accessions have had over 30% seed germination over two successive years. Seed yield has averaged 330 pounds per acre, with approximately 454,000 seeds per pound. Read the USDA Plant Fact Sheet for more information about using gulf cordgrass in restoration projects.
