Fernleaf lavender is a bit unusual compared to its lavender cousins. The foliage is the first thing one notices, with highly dissected, fern-like leaves growing one to two feet tall and wide. The blue-violet flower spikes are closer to French or English lavender flowers in looks, rising on stems up to 18" tall, and can be used for culinary purposes. This variety loves the sun just as other lavenders do, however; it does better in soils with more organic materials, contrary to other lavenders that grow just fine in poor soils. Fernleaf lavender is also more sensitive to the cold, and needs shelter when the temps drop down to 20 degrees or lower. Just like other lavenders, this variety is highly fragrant, deer-resistant, and a magnet for butterflies in the summer.
