1/10 gram per packet, approximately 600 seeds
Large yellow flower clusters stand out against feathery green foliage. This low maintenance perennial has a clumping habit. Direct sow in fall or spring, or start inside and transplant 18-24 inches apart. Germinates when soil is between 65-75 degrees F. Surface sow and cover very lightly with soil, as the seeds need light to germinate. Blooms begin in early summer. Butterflies love these flowers!
