- Herbaceous perennial
- USDA hardiness zones:
ëSummer Love is an upright, clump-forming perennial that grows to 30-36î tall. It features a long summer-to-fall bloom of tubular, 2-lipped, reddish purple flowers on stems clad with aromatic (mint scented), lance-shaped to ovate, bright green leaves. Flowers bloom in whorls on erect, salvia-like spikes (to 12î long). Flowers are attractive to bees, hummingbirds and butterflies. Agastache comes from the Greek words for ìmuchî (agan) and ìgrain stalkî (stachys) in reference to the flower spikes. U. S. Plant Patent Applied For (PPAF).
- Full sun to part shade
Best grown in fertile, medium moisture, well-drained soils in full sun to part shade. Best in full sun. Good soil drainage is essential. Plants will perform poorly and may not survive winter in unamended clay soils that retain moisture. Plants tolerate heat and some dry soils once established. Deadhead spent flower blooms to promote additional bloom. Plants may not be reliably winter hardy throughout the St. Louis area where they should be planted in a protected location (e.g., southern exposure). Leave leaf and flower stems up during the winter for additional protection, cutting back the dead stems in late winter to early spring. Sandy/gravelly mulches will protect plants and help to avoid onset of rot. Plants may also be grown in containers. Take cuttings from containers in late summer for overwintering.
