why we love rose mallow
The rose mallow is a shrub-like stunning bloomer with clumping stems that reach three to six feet tall, depending on the variety. It is commonly called tree mallow because of its upright growth habit. Originally native to the Mediterranean, rose mallow seeds have naturalized and now grow wild across much of the US. With its tropical-looking bold pink blossoms, this plant is an eye-catcher, blooming throughout the summer and attracting pollinators such as hummingbirds to the garden. Rose mallow makes a great cut flower.
planting rose mallow seeds
Rose mallow seeds can be direct sown in the garden in early spring when a light frost is still possible in colder climates, where it is grown as an annual (zones 4 through 6). Those in milder climates can seed in the fall and enjoy blooms in late winter and spring. Rose mallow works as a perennial in zones 7 through 9 but will require replanting after five years or so. These plants tend to have very sensitive roots and therefore do not like to be transplanted. If seeding indoors, do so six to eight weeks before the final frost-date. Prepare seeds by soaking them for 24 hours before planting. Nicking the seeds with a sharp knife or other abrasive tool can aid germination. Seed in groups of three to four and thin after germination. Do not cover seeds, as they require light to germinate. Germination takes between 15 and 30 days, depending on soil temperature.
how to care for rose mallow
Rose mallow prefers full sun but enjoys afternoon shade at the height of summer. These plants do well in most well-drained soil types, including nutrient poor soil. If direct sowing, thin out the weakest seedlings to 18 to 24 inches between plants when they’re about four inches tall. Rose mallow is drought-tolerant but likes regular water during the establishment phase and during hot, dry months. Aim for about one inch of water per week. Deadhead to promote continuous blooming throughout the season. Rose mallow may self-seed in warmer locations.
