Hollyhocks (Alcea rosea) are classic, old-fashioned garden favorites, renowned for their tall, striking flower spikes that bring vertical drama to borders, fences, and cottage gardens. The Single Petal variety features open, delicate blooms in an array of colors, including pinks, reds, whites, and yellows, attracting pollinators like bees, butterflies, and hummingbirds. These biennial or short-lived perennials bloom profusely in their second year, growing up to 6-8 feet tall. Their vibrant flowers evoke a timeless charm, perfect for traditional and contemporary garden designs alike.
