Malva moschata aka Musk Mallow

Malva moschata, or musk mallow, belongs to the mallow family. This short-lived perennial grows upright and forms a bushy clump. Kew places its native range from Europe to western Türkiye. Garden sources also include North Africa within its native range. It has spread into fields and roadsides across North America. In gardens, it grows 2–3 feet [0.61–0.91 metres] tall. RHS gives an upper height of 3.3 feet [1 metre]. Its spread reaches about 1.5–2 feet [0.46–0.61 metres].

The plant loses its leaves at the season's end. Its base can become woody, while stems stay light green. Stems may be round or angled, with few hairs. Rounded leaves grow near the base of the plant. The stem leaves divide into five to seven narrow lobes. Their edges have teeth, and their veins spread like fingers. Leaves grow alternately and smell musky when crushed. Their lower surfaces may carry a few fine hairs.

Pink flowers open from June through September. Sources also record white flowers for the species. The flowers have five notched petals around a central stamen column. They form singly or in groups at upper leaf joints. Their scent has the same musky note as the leaves. Flowers attract bees and butterflies throughout the bloom season. Each flower later forms a ring of seed-bearing mericarps. These small, smooth fruit sections have a kidney-like shape.

Grow musk mallow in full sun and well-drained soil. It also accepts partial shade and dry to moist conditions. It grows in sand, loam, clay, or chalk. RHS lists acid, neutral, and alkaline soils as suitable. Rich soil may make the stems need support. Hot, humid summers can limit its growth and performance. Hot, dry weather may cause the leaves to yellow. Sources list USDA zones 3–8 and UK hardiness H5. Use it in borders, cottage gardens, or wildflower plantings. Removing faded flowers helps it keep blooming. It seeds freely where conditions suit it, replacing short-lived plants.

Serious pest problems are uncommon, but Japanese beetles can cause damage. Aphids, rust, stem rot, and other fungal diseases may occur. Leaves and flowers can go into salads; seeds are edible too. Leaves can also be cooked, and young seeds taste nutty. PFAF warns that leaves can gather nitrates in nitrogen-rich soil. It records traditional medicinal uses for leaves and flowers. The plant also supplies dyes and stem fibre for cordage.
