Hibiscus laevis (Smooth Rose Mallow) [15 Seeds]


Germination Information: Sow these seeds 1/8 to 1/4 inch deep in warm, bright conditions indoors from late winter through spring or outdoors in summer. Soaking the seeds in water for 12 to 24 hours before sowing and/or providing extra warmth from a heat mat can help to speed germination.

The last time I started this species from seed, I sowed on May 1—under lights and on a heat mat—and the seeds germinated on May 5. Your experience may vary.

The distinctive blooms of native rose mallows (Hibiscus) are a delightful sight in late-season gardens. This species—H. laevis, commonly called smooth rose mallow or halberd-leaved mallow—is one of my favorites. It typically reaches about 5 feet tall by bloom time (August and September here in PA), with deeply lobed leaves and soft pink flowers that have darker pink centers. The large seedpods that develop later are also interesting, and the foliage can develop showy yellow fall color. Overall, smooth rose mallow is a much more refined-looking alternative to common rose mallow (H. moscheutos) and is right at home in a moist-soil border or rain garden. Native to the eastern half of the US. Full sun; moist to wet soil. Perennial; Zones 4 to 9.

Collected in mid to late September 2022. At least 15 seeds. Unknown ecotype.
