Agastache Black Adder
Dramatic flower spikes from dark buds.
Black Adder Agastache produces upright spikes of smoky violet-purple flowers that emerge from nearly black buds, giving the plant a deeper, more dramatic look than many lighter blue Agastache varieties. The tall bottlebrush-style blooms bring strong vertical color to sunny borders from summer into early fall.
A pollinator magnet with real garden movement.
This perennial is a standout for bringing bees, butterflies, hummingbirds, and beneficial insects into the landscape. The nectar-rich flower spikes keep pollinators active through the warm months, making Black Adder Agastache a smart choice for pollinator gardens, hummingbird plantings, and wildlife-friendly borders.
Fragrant foliage deer tend to avoid.
The aromatic green foliage has a minty, anise-like scent when crushed, adding another layer of interest beyond the flowers. That strong fragrance also helps make Black Adder Agastache less appealing to deer and rabbits, especially compared to softer, less aromatic perennials.
Built for full sun and well-drained soil.
Black Adder Agastache thrives in full sun and performs best in well-drained soil that does not stay wet, especially during winter. Once established, it handles heat and dry spells well, making it a strong fit for low-water gardens, sunny slopes, dry borders, and leaner garden soils.
Easy to pair in colorful perennial designs.
The rich purple flower spikes pair beautifully with coneflowers, black-eyed Susans, yarrow, catmint, salvia, ornamental grasses, and Russian sage. Use it in groups for a bold pollinator display, or repeat it through a sunny border to add rhythm, height, and late-season color.
