More About Crimson Pigmy Barberry...

'Crimson Pygmy' is a smaller, dwarf version of the original Red Barberry with the same exceptional drought tolerance and handsome dark, blood-red foliage throughout the wearm season. Fall foliage is a brighter red. It forms a neat, compact, mound in the garden to about 2 feet tall by about 3 feet wide at maturity. 

It's low and mounding habit make Crimson Pygmy a perfect selection as a low-growing border or , since it loses it's leaves in winter, it can be planted behind low-growing junipers such as 'Blue Rug', 'Bar Harbor', or 'Green Mound'. The plant has little barbs on the branches so it also serves well as a low border that will deter the neighbors pets and their children if necessary:-)

Crimson Pygmy is very easy to grow and maintain. It prefers rocky or sandy well drained soils and full sun for the deepest foliage color. Keep soil damp during the first summer and then the plant will require little if any supplemental irrigation. Because it maintains a neat mounded shape on it's own and is exceptionally drought tolerant, it is very low maintenance.
