Big Bend Barometerbush

Description

Big Bend silverleaf is the most cold hardy of the Leucophyllums and has wintered over in Amarillo, Zone 7, for 5 years so far. Possibly cold hardy to Zone 6. It is hard to beat a more attractive summer blooming shrub for small xeric spaces. After summer rainfalls, Big Bend silverleaf, native to the Big Bend National Park area, becomes covered in silver blue flowers that twinkle like jewels among its silvery gray leaves. Hard to find, it's worth searching for. Other Leucophyllums, commonly referred to as Texas Ranger, or Cenizo (of which there are many varieties) are usually not cold hardy in the Texas Panhandle.
