Loveliness Lavatera Seeds (Pink). This very showy tender perennial has flowers reminiscent of hibiscus. Lavatera is also known as annual mallow or rose mallow. Beautiful pink hibiscus-like blooms up to 7 cm (3") across cover these bushy, multi-branched plants all summer long and well into fall. Prefers full sun but will tolerate partial shade and makes its best growth in cooler weather. In regions with very hot summers, we suggest successive sowings every two weeks to help maintain continuous blooming. Avoid transplanting after establishment as Lavatera roots form extensive tangled networks.
