GIANT HYSSOP SEEDS

Agastache scrophulariifolia

Big fragrant North American native that is beloved by diverse winged creatures. Attractive clumps of anise-scented leaves erupt in spring and can ultimately grow to 6'. Flowers in shades of pale lilac through deep purple, usually in August through September, but occasionally much earlier if plants are stressed (as they are in this photo taken in late June -- look at the poor Amsonia!). Both leaves and flowers are edible and suitable for tea. Spectacular companion and fair competition for big native Asteraceae like Cup Plant and Maximillian Sunflowers. Best in rich moist soils in sun or in dry bright partial shade on the edge of a woodland. Plants will suffer given both dry soil and full sun.

These seeds require stratification to germinate. Sow into pots of moist soil, just barely cover with fine vermiculite, and mist generously. Cover with plastic to maintain moisture and place pot in a sheltered location, like a screened porch or cold barn, to overwinter. Seeds will begin to germinate during the first warm days of spring. Seedlings with true leaves should be pricked out and transplanted into individual pots or cells to grow on in part sun outdoors. Pinch leggy plants to encourage branching and water regularly but do not allow soil to become waterlogged. Transplant around the date of the last spring frost.

Take care to give these plants plenty of space because they can essentially grow to the size of a small shrub. Not the best Agastache for small gardens (Agastache foeniculum would be a better choice), but really excellent in a native insectary border. Hardy to at least zone 4. Cut back hard in winter.

Packet contains at least 500 seeds.
