Rose Mallow (Lavatera Trimestris Tanagra) - This tropical looking flower is a joy to grow from Rose Mallow seeds! This shrub-like annual grows quickly and blooms heavily with large, deep rose colored blooms. Rose Mallow is related to Hibiscus and Hollyhocks, and it is a prolific bloomer - like a Hollyhock on steroids! It is also known as Annual Mallow. Lavatera Trimestris Rose Mallow is highly prized for its exceptional blooms. The plant does well in soils that do not drain well and in marshy areas or near ponds.
Rose Mallow is easy-to-grow from flower seeds. Plant Lavatera Trimestris seeds directly outdoors as the seedlings do not transplant well. After the last frost has passed, prepare garden site, loosening soil. Sow 3 - 4 Rose Mallow seeds in a group, spaced 18 - 24 inches apart. Barely cover the Rose Mallow flower seeds and keep them moist until germination occurs. Thin to strongest plant. Deadhead spent blooms to encourage longer bloom season. If a few blooms are left to re-seed, the Rose Mallow plant will often grow again the following season.
