This rare native species found only in a few areas of the Midwest is a must for brightening the late summer garden. Its scarlet-red flowers are extremely showy and will attract hummingbirds eager to feed from the nectar-rich blossoms. Plant in enriched, well-drained sandy or loam soils and irrigate regularly if conditions are dry. A wonderful flowering companion for Agastache 'Black Adder'.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
