150 (200)cm, White Hollyhock is a white flowering form from Alcea rosea which may spontaneously occur in nature. As the normal form it is biannual to semiperennial species found in open, rocky spots throughout the Mediterranean. It makes an impressive stalk with very large, pure white flowers. Easily grown in any rich, well drained soil in a sunny spot. Seeds are from a single white flowering plant found within hundreds of normal winred specimens. It may naturally split up (but not necessarily) into various shades of white, pale rose to winered in the second generation. VII-VIII.
