I have a planting bed from driveway and along the porch (9 x 14), then continues along front and side (3 ft) of pier and beam home, the corner between the front and side orients southwest so I receive full sun in both the front and side beds,I am considering compact Texas sage but I am concerned about over-watering during the summer when I water the foundation here in Fort Worth, Any thoughts? (The porch is about 14 inches and serves as entry and can also be used as a generous sitting area in front of home.)
