Agastache ‘Heatwave’

Agastache hybrida

Agastache ‘Heatwave’ is distinguished by large bright magenta flowers and a broad upright growth habit. It has a long flower period, and even after it has finished flowering, the pink calyxes stay on the plant. Plants are very heat tolerant and prefer full sun. They have an upright habit and reach 18 inches tall at maturity. Equally good in the border, and as a candidate for container growing. The better the drainage the happier the plant. Attractive to hummingbirds and butterflies, with wonderfully spicy fragrant licorice scented foliage.
