Some of the showiest flowers of the spring to early summer garden. Plant as early as possible after the ground thaws for best results. Ours are planted in full sun, but we’ve seen them blooming happily in partial shade They are more perennial when planted in raised beds in well drained soil. 8/+cm tubers; 10 per sq. ft; if in whz 3-6 plant them in the spring; if in whz 7-10 plant them in the fall (they are available then, also!) or VERY early spring. They will perform best if soaked overnight prior to planting.
