Fernleaf lavender (Lavendula multifida) is also commonly known as French lace lavender. The names refer to its fern-like leaves, which are grayish-green, deeply lobed, and can be described as lacy. You can grow fernleaf lavender in your herb garden and harvest both the flowers and leaves. Use them in cooking or in soaps and other care products, potpourri, and scented sachets. This lavender need not be limited to herbal uses, though. It’s a woody shrub that can be used as a low hedge, border, or edge—fernleaf lavender grows up to about two feet (60 cm.) tall and wide. Grow it in clumps for visual interest and garden fragrance. In warm climates, it will produce pretty flowers year-round.
