One of the most popular hollyhocks of all time, 'Chater's Double' was named after the English horticulturist, Chater of Essex, who developed this variety in 1880s. Colors include golden-yellow, rose, maroon, salmon-pink, scarlet, and white. Flowers have a long bloom period and are edible! Fairly drought tolerant but performs best with ample moisture and rich soil. Hollyhock flowers are edible, but very bland; however, the large, colorful petals are lovely garnishing salads or desserts. (The flower's central disk, while edible, can be bitter.)
