Blue Hyssop Seeds — Agastache foeniculum

A Fragrant Favourite for Bees & Butterflies

Blue Hyssop (Agastache foeniculum) is a wonderfully aromatic perennial herb that earns its place in any cottage or pollinator garden. Tall spikes of soft violet-blue flowers rise above anise-scented foliage from midsummer through to autumn, creating a haze of colour that bees and butterflies simply cannot resist. Beautiful, fragrant, and incredibly easy to grow.

Growing Tips for New Zealand

Sow seeds on the surface of moist seed-raising mix in spring — do not cover deeply as light aids germination. Transplant seedlings to a sunny, well-drained position once large enough to handle, spacing 30–45 cm apart. Blue Hyssop thrives in full sun and tolerates dry conditions well once established. Cut back after flowering to encourage a second flush and prevent excessive self-seeding. A short-lived perennial that self-seeds freely in warm NZ gardens.
