Alcea rosea
As Missouribotanicalgarden says Alcea rosea grows in average, medium moisture, well-drained soil in full sun. Tolerates a wide range of soil conditions and some light shade, but will not tolerate wet winter soils. Considered a biennial or short-lived perennial. If grown from seed, plant seeds in August or September for bloom the following year. Although short-lived, hollyhocks easily self-seed and can establish colonies in the garden that persist for years as if they were perennials. Alcea rosea, commonly called hollyhocks, are old garden favorites. The flowers grow on rigid, towering spikes or spires which typically reach a height of 5-8' tall and usually do not require staking. Foliage features large, heart-shaped (3, 5 or 7 lobes), rough lower leaves which become progressively smaller toward the top of the spire. Long bloom period from June to August.
