Golden Jubilee Purple Giant Hyssop 5 Seeds, Agastache foeniculum

Agastache rugosa, commonly called purple giant hyssop, is an upright, clump-forming, herbaceous perennial that typically grows to 2-3' tall. Leaves and flowers are aromatic. It is native to moist grasslands, valleys and stream banks in China, Vietnam, Laos, Korea and Japan. Fragrant, tubular, 2-lipped, violet-pink flowers bloom summer-to-fall in whorls on erect, terminal, salvia-like spikes (each to 2-4” long) atop strong, rigid stems. Flowers are attractive to bees, hummingbirds and butterflies. Aromatic (anise scented), toothed, lance-shaped to ovate leaves (to 3" long) are blue green.

Culture
Easily grown in average, 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 hard clay soils that retain moisture. Plants tolerate heat and some dry soils once established. Deadhead spent flowers to promote additional bloom. Plants may not be reliably winter hardy throughout Zone 5 where they should be planted in protected locations (e.g., southern exposures). Leave flower and leaf 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 (pinch back foliage tips in spring to limit mature plant height). Take cuttings from containers in late summer for overwintering. Plants will spread in the garden by self-seeding.

SOWING ADVICE
For best results, sow seeds in good light at any time onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. Keep soil moist until germination occurs. Seeds should ideally germinate in between 2 and 6 weeks although they make take considerably longer. Pot on seedlings before finally planting out into a container or a well-drained spot.
