Description:

Blue Giant Hyssop is a long-blooming, perennial herb known for its bright lavender-blue flowers and fragrant leaves. Spikes of the tubular, lavender-blue flowers bloom July-September; the flower spikes are good fresh-cut or dried for floral arrangements. The flowers are a good nectar source for bees, butterflies, and hummingbirds. Blue Giant Hyssop has special value to native bees and bumblebees. The leaves have a strong anise fragrance; they can be used to make herbal teas. Blue Giant Hyssop thrives in full sun and well-drained soil, and is drought-tolerant. It is a good choice for the dry, sandy soil conditions of seashore gardens. Use Blue Giant Hyssop in borders, herb gardens, or containers.
