Non-spreading in habit, this will remain evergreen in mild winter regions. Requires good drainage, especially in warm summer regions. Clumps may be easily divided in spring. In cold regions the foliage sometimes needs to be tidied up with scissors in spring, but quickly regrows.

We do NOT SHIP plants. ALL Sales are in person at our garden center.
