Title: Mountain laurel planting over Frederickburg limestone
Answered by: Brigid & Larry Larson

QUESTION:

We have rocky limestone shelves on our property. We want to plant a mountain laurel. Are the roots strong enough to break through the limestone or should we try to find another location? The limestone is about 14-16 inches under regular soil.

ANSWER:

Mr Smarty Plants thinks your chances of the Sophora secundiflora (Texas mountain laurel) rooting and thriving over a limestone shelf are pretty good.  The plant record has that "It is drought-tolerant, prefers rocky limestone soil, and is native from Central Texas west to New Mexico and south to San Luis Potosi in Mexico."  Even in shelves, the limestone tends to have cracks, holes or separations and the Texas mountain laurel roots are adapted to find and penetrate these opportunities.    14-16 inches of soil is quite a bit when compared the pure rocky soil of the Hill Country where they are known to thrive.  This write-up in a Aggie Horticulture record has similar comments.

  To that end, here are previous Mr Smarty Plants answers where Mountain laurel was recommended for a shrub in Frederickburg and as a candidate as a screen plant in Comfort.

I'd give it a try!
