Blue Cushion Lavender

Evergreen Plant, shear to maintain size after flowers fade. This may also promote a second flush of flowers later in the season. Shear to just below the tips of the foliage to keep plant bushy, Lavender will not grow new foliage on old wood so do not prune back to branches without foliage inside the plant
