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: How much shade will Thunder Turf (Habiturf) take?
Answered by: Guy Thompson

QUESTION:

How much shade will Thunder Turf take?

ANSWER:

Not much!  Thunderturf, or Habiturf, as it is also called, needs a minimum of six hours of direct light to grow well. It will grow somewhat sparsely if given strong indirect light below a high tree canopy.  We know of no native turf grass that thrives in shade.  You would be well advised to consider a non-grass ground cover in shady areas.  Paspalum setaceum (Thin paspalum) is a bunch grass that is common in Central Texas and should occur in shady areas of Arlington.  Its compact roseate form is mowable, but some find the 12-15 inch-high seed stalks unattractive.  Grass-like sedges do grow well in shade.

Here are several groundcovers that will grow in the shade.  Except for the two grasses, they are semi-evergreen or evergreen.

Calyptocarpus vialis (Straggler daisy) is evergreen to semi-evergreen. "Evergreen in areas with mild or no winter, deciduous in areas with cold winters."

Phyla nodiflora (Texas frogfruit) is semi-evergreen.

Packera obovata (Golden groundsel) is evergreen to semi-evergreen.

Carex planostachys (Cedar sedge) is evergreen.

Carex texensis (Texas sedge) is evergreen.

Salvia lyrata (Lyreleaf sage) is semi-evergreen.

Ruellia humilis (Fringeleaf wild petunia) is evergreen.

Chasmanthium latifolium (Inland sea oats) dies back in winter but is perennial.  This grass grows in clumps and can reach 2 feet or more, but is very attractive.

Muhlenbergia schreberi (Nimblewill) dies back in winter but is perennial.
