Maintenance

This short lived perennial will decline if allowed to dry out. Heavy mulch causes crown rot and rich, organic soils encourage rank, vegetative growth. Plants need to be divided at least every other year.

Comments

The numerous, narrow, light green leaves of this perennial form dense, tufted clumps of new foliage. The light blue, star shaped flowers bloom a few inches above the leaves.
