In the garden
Sidalcea malviflora is a perennial herb native to western North America that produces multiple stems topped with clusters of pink, five-petalled flowers. In the UK it reliably flowers from June to August and typically reaches around 0.8 m in height at maturity. Plant it in a sunny spot; the species prefers full sun exposure and performs on sandy, loamy or clay soils so long as they are kept moist but well-drained. Its UK hardiness rating is H7, meaning it is fully hardy through our winters; it also corresponds to USDA zones 5–9 where applicable. Allow space for individual clumps to expand and avoid heavy waterlogging at the roots, especially over winter. Use Sidalcea malviflora as a mid-border perennial where upright flower stems can rise above lower neighbours, or alongside other sun-loving herbaceous perennials that share its moisture needs. Cut back spent flowering stems if you prefer tidier clumps; leaving seedheads in place will encourage wildlife interest. Allow at least 0.8 m of vertical space when siting the plant to accommodate its mature height and summer display.
