Flowering Season

From Early Winter TO Mid Winter

This one flowers late in the year, around late early winter, so frost may kill the flowers in some areas. After flowering, you may cut the plant back to the ground, and new growth will shoot up in the spring.

 

Planting

From Early Spring TO Early Spring

Plant your tree between 8 and 12 inches deep, and mulch it heavily.
