Description
Black Adder Hyssop is a standout perennial for Massachusetts gardens, offering striking smokey lavender flowers on dark purple spikes from mid-summer to fall. Its fragrant green foliage releases a subtle licorice scent, enhancing sensory appeal. This drought-tolerant plant thrives in full sun and well-drained soil, making it ideal for low-maintenance landscapes. Hummingbirds, bees, and butterflies flock to its nectar-rich blooms, while deer tend to avoid it.
Perfect for mass plantings, herb gardens, and containers, Black Adder Hyssop reaches 3 feet in height, with flower spikes extending to 4 feet. It spreads up to 24 inches, creating a beautiful vertical element in garden beds. Low maintenance and cold-hardy to zone 5b, it returns year after year with vibrant color. Prune lightly in early spring to encourage fresh growth and maintain a compact form.
