The species name Agastache comes from the Greek aga, or numerous, and stachys, an ear of grain, an apt name for this floriferous tribe.

Depth:
Surface sow and lightly firm in. Requires light to germinate.
Sprout Time:
7-21 days
Starting Indoors:
Sow in pots, 6-8 weeks before last springtime frost. Keep at 65-70°F with evenly moist conditions by placing a humidity dome over the containers until germination occurs. Or use a light sprinkling of fine vermiculite over seed tray.
Starting Outdoors:
Sow in desired growing location after all danger of frost has passed.
WHEN TO SET OUTSIDE
In springtime after all danger of frost has passed.
PLACEMENT & CULTIVATION
Agastache grows best in freely draining, gritty soils, where it will grow upright. Rich, moist soils encourage a more sprawling habit and can decrease flowering. To ensure the best overwintering success, choose a sunny, sheltered position in northern gardens and plant in a raised bed or amend loamy soils with generous amounts of sand, gravel, and some compost. A winter mulch of pine needles or stone is best in wet winter regions, as they do not harbor much moisture. Wait until spring to cut down to further encourage its perennial nature. This pollinator-friendly plant unfailingly attracts hummingbirds, butterflies, and bees, while the minty, anise-scented foliage is unappealing to deer and rabbits. In their first year of growth from seed, perennials bulk up their roots to flower copiously the following year. Larger transplants planted after frost will produce loads of flowering spikes the first summer and fall. Deadhead spent blooms.
Final Spacing:

Water Requirements:
Low Water Use
Watering Details:
Agastache is drought-tolerant once fully established. During the first season, water regularly. However, they can withstand prolonged dry spells with minimal water once they mature. If there are extended periods of drought, provide mature plants with a deep soaking every two weeks.
Soil pH:
Slightly acid to slightly alkaline 6.0-7.5 pH
Fertilizer:
Apply a 1/2" layer of compost annually.
Diseases & Pests:
Agastache are generally not susceptible to pests or disease but can be affected by mildew if summer weather is dry. This can be avoided by preventively spraying with a baking soda or organic fungicide every two weeks, depending on local weather conditions.
When to Cut for Bouquets:
Harvest when 1/3 to 1/2 florets are open.
