A true tallgrass prairie species, Rattlesnake Master grows from 3 to 5 feet tall, with flowers that have a sweet aroma that attracts various pollinators. Its habitats include rocky woods, moist to slightly dry black soil or sand prairies, savannas and limestone glades. Plants are best in full sun, with dry to moderate moisture and well-drained, poor sandy soils. It is best left undisturbed once established due to its large taproot. Native Americans used fibers from the leaves and used the roots for medicinal purposes.

Sowing: Direct sow Rattlesnake Master seeds in late fall, planting the seeds 1/4" deep and lightly compacting the soil. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before direct sowing; keep the soil consistently moist until germination. Thin or transplant the seedlings.

Growing: Water seedlings occasionally until they become established. Mature plants tolerate heat and drought, though they appreciate watering in dry periods. This plant adapts well to sandy, rocky, or clay soils. It may self-sow in good growing conditions, and makes an excellent choice for prairie plantings, landscaping, or perennial gardens. It attracts bees and butterflies, as well as resisting deer.

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
