OSC Lavatera Mont Blanc
This very showy tender perennial has flowers reminiscent of hibiscus. Lavatera is also known as annual mallow or rose mallow. Beautiful white 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. Hot temperatures speed the blooming cycle so 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. Lavatera will sometimes overwinter in Zone 6 but is grown as an annual in most of Canada.
