Yellow Giant Hyssop
An exclamation mark in the landscape throughout the winter, Agastache nepetoides (Yellow Giant Hyssop) is a tall herbaceous perennial boasting vertical spikes, 4-16 in. long (10-40 cm), packed with tiny, pale yellow flowers. Blooming for about 1-2 months from mid-summer to fall, they are borne atop stiff, square stems and attract bees, butterflies, and other beneficial pollinators. The tiny flowers are not particularly showy because only a few of them are in bloom at the same time. The beauty of Yellow Giant Hyssop consists primarily of its foliage of toothed, arrowhead-shaped, medium to dark green leaves. Unlike most mint family members, Yellow Giant Hyssop lacks their minty fragrance. The flowers give way to small seeds that will readily self-germinate in the spring. The root system of Yellow Giant Hyssop is fibrous and rhizomatous, allowing the plant to spread and form colonies without being aggressive.
