Seeds harvested from the biggest and best blooms at A&J Homestead last year. Dinner Plate Hibiscus (Hibiscus moscheutos) is a cold-hardy, herbaceous, flowering perennial plant known for its giant, show-stopping blooms. Fresh stems sprout from the ground in late spring, quickly creating a small rounded shrub. The plant then blooms in late summer with huge, 8″-12″ wide blossoms in pink, white, or red.
