25 Seeds Double Scarlet Hollyhock, Alcea rosea, Perennial Tall Blooming Flower

Double Scarlet Hollyhock is a classic cottage garden favorite, producing towering spikes of fully double, ruffled scarlet-red blooms that add dramatic height and old-fashioned charm to any landscape.

These perennial plants are perfect for back borders, fences, or as a striking focal point. Hummingbirds and butterflies love them, and they make excellent cut flowers. Hollyhocks thrive in well-drained soil and full sun, and while they may bloom the first year from an early indoor start, they often establish foliage the first year and burst into glorious bloom the second, returning reliably for years.
