From the garden
TheKnoxCountySafety Rest Area landscape qualifies as a xerophytic mini-botanic garden. Xerophytic plants are those that are able to survive in environments with little water. The term ‘xerophyte’ comes from the Greek xeros, meaning dry, and phyton, meaning plant.
The Knox County Safety Rest Area, on westbound US 82 east of Benjamin, is a showcase for established xerophytic plants. The species chosen by TxDOT (txdot.gov) for landscaping the rest stop are especially well suited for our arid West Texas.
Gardeners and casual outdoor enthusiasts can pack a lunch and take a drive to enjoy a well-maintained roadside table at the rest stop. Depending where you are in the readership area, the drive is a short one, for example, a one-hour drive from Dickens. The rest stop is handicap accessible, with interpretive displays, drinking water, and group picnic areas. With paper and pencil and a camera make a list of the drought tolerant plants that might be included in a personal West Texas garden or landscape.
