Sowing and Growing

Sow seeds directly in the fall as stratification will aid germination, or start artificially stratified seed inside. Germination will take between 2-3 weeks. Marshmallow grows up to 3-4’ tall, as pale-pink flowers appear up and down the stalk in mid to late summer. This herb likes to be grown in full sun, but it can stand partial shade and thrives in cooler regions.


Marshmallow is known for its medicinal benefits which includes soothing the gastrointestinal tract and the throat. It also has culinary uses. Green leaves and pink flowers can be harvested anytime during the growing season. Dig up marshmallow roots in the spring or fall. All parts can be dried for winter use.
