Lavender is often the go-to evergreen plant for parking strips, dry hillsides, and any sunny spot that may get a bit neglected. An indispensable evergreen landscape choice, lavender's fragrant leaves and flowers serve double-duty and can be used in cooking, or dried and used in sachets and potpourris. 'Ana Luisa' Lavender stands out from other lavenders with silvery gray foliage that seems almost white at times, making the bluish-purple blooms pop. Flowers will ride high on foot tall stalks from late spring until fall, attracting bees, butterflies and hummingbirds. By all means, harvest the flowers, and don't be afraid to trim back the foliage as well.
