'Martha Roderick' is a very reliable, dense, mounding lavender growing to about 18 inches tall and 24 inches wide. It has powdery gray-green narrow, smooth foliage and fuzzy light lavender-blue flower spikes that bloom from June until September. Both foliage and blooms are deeply aromatic, especially when crushed.
Lavenders thrive in full sun and poor soils, though a little kindness will be rewarded with a bounty of flowers. Plant in well-drained soil. Cut back 1/3 to 1/2 size in spring when new growth begins to emerge. Does not like to be divided, though sometimes stems that touch the ground will root, and these can be snipped from the parent plant and transplanted. Deer resistant.
