Malva moschata 'Rosea', or Musk Mallow, is a leafy, much branched perennial native to Europe and Northern Africa. Stems are hirsute with spreading simple hairs. Basal leaves are reniform and are shallowly 3-lobed. Upper leaves are palmately 5-7 lobed from 0.8-3.1 inches (2-8 cm) long and wide. 'Rosea' is a cultivar of the standard Malva moschata which has white flowers. Whether the plants are grown in containers or in the landscape, they will reach 24-35 inches (6-90 cm) tall. These are very easy plants to grow and very showy when in flower. Plants are hardy in the landscape in USDA zones 3-10.
Blooming Time: Plants have a long blooming period and in zone 7 they will bloom most of the summer. Blooms are axillary and are 1-2 inches (2.5-5.1 cm) across. Flowers have a slightly musky scent.
Culture: Malva moschata 'Rosea' needs full sun to partial shade with a moist soil. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. The plants are kept moist at all times and should never be allowed to dry out. We fertilize the plants on a monthly basis with a balanced fertilizer. Once the blooming period is over, plants should be cut back to just above ground level. This should be done even if the plants are grown in containers. Once plants are cut back they placed in the cold room for a winter dormancy period. Plants should be kept moist during this period and fertilizer should be withheld.
Propagation: Malva moschata 'Rosea' is propagated from cutting in spring or division of large clumps and by seed.
