Seeds from these wonderful Alcea rosea Creme de Cassis. Although technically biannuals if you let these reseed you can have them every year. No pretreatment necessary, just sow seeds just below the soil surface at 70 degrees and water. These 2-tone, semidouble and single blooms are all found on a single stem. 3 to 4 inch flowers are white with raspberry veining and a yellow eye. Will produce more flowers in cooler climates. These are biennials that bloom in July to September in full sun.
