Hollyhock

A must-have for cottage gardens and planting along sunny fences and walls, hollyhocks add charm and color to the mid to late summer garden. These classic perennials produce spikes of single or double flowers and return year after year. They're spectacular as cut flowers and will enliven cut-floral displays. Growing up to 8 ft. tall, hollyhocks are sometimes planted as a backdrop for other flowering plants. They're available for sale in an array of flower colors and in single and double flower forms. When buying hollyhock perennials for sale online, make sure they are suitable for your grow zone. Other factors to consider are their flower color and mature height and spread.
