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.

Title: Groundcover for shade in San Antonio
Answered by: Nan Hampton and Joe Marcus

QUESTION:

I have a large red oak tree in the front yard. It is keeping any sun except filtered underneath. Faces n/w and in san antonio. I need a ground cover that is drought tolerant and likes the shade and heat.

ANSWER:

Mr. Smarty Plants thinks that this sounds like a job for sedges.  Here are a few suggested ones:

Carex planostachys (cedar sedge)

Carex texensis (Texas sedge)

Some broadleaf possibilities are:

Calyptocarpus vialis (Straggler daisy)

Geum Canadense (White Avens)

Salvia lyrata, (Lyre-leaf sage)

Salvia coccinea, (Scarlet sage)

Salvia roemeriana, (Cedar sage)
