Marshmallow
Marshmallow
A tall biennial, about 1.2 to 1.5 m, with showy pink saucer-shaped flowers among large, heart-shaped, pointed leaves. It was the original source of the sweet marshmallow, and the leaves and roots are used for their soothing effect on the throat and digestive tract. Sow into trays in autumn for flowering the following summer, prick out at 2.5 cm diagonal spacing and transplant at 6 cm high, 30 cm apart on the diagonal.
