24″ x 20″, flowers to 3′ There are 2 varieties of Fern Leaf Lavender, L. multifida and L. pinnata. We grow both. The differences are slight with multifida foliage a little coarser and grayer, and pinnata more finely cut and gray green. Both are great lavenders for Hawaii. Nearly non-stop blue lavender flowers atop tall airy stems. Groom plants by cutting back old flowers and slightly into foliage. Do not cut into old bare wood. Fertilize after pruning and the flowers will come again.
