Dictamnus albus varieties grown in Zones 3-8 and reach 15-36”h x 24” w. They have an upright form and a slow growth habit. They are grown for their flowers and foliage. Their roots resent transplanting and disturbance. Plant them in groups in the border for best effect. Companions include ‘Fire King’ yarrow, beardlip penstemon, smooth white penstemon, and ‘Hameln’ fountain grass.

Dittany Care

Plant dittany 18-24” apart in spring or fall. Feed them with slow-release granular plant food at time of planting or begin using water-soluble plant food 3 weeks after planting in spring. Cease feeding 6-8 weeks prior to the first frost date. This low-maintenance perennial is drought tolerant once established, but new transplants require ample and frequent moisture.
