Scientific name: Althaea officinalis

The family which marshmallow belongs to comes with many health benefits and few toxicities if any. It is sweet and can be used both internally and externally, as food and medicine.

Back in the day, before it became a sugary chewy thing melted over a camp fire containing no actual marshmallow plant, it was eaten as a root vegetable. Later on, it was used to create a sweet light confection and was helpful for coughs and digestive issues, even in infants.

How to Grow


Where do you live?

Marshmallow is a pretty perennial with white or pink flowers that grows best in zones 5-8 but is not very picky. Make sure you make room as it can grow 4 feet tall.

Put em in the ground

Seeds must be exposed to a winter-like period before they will sprout, so it’s easier to start with young plants from a nursery. Ensure you purchase this variety if using for medicinal purposes. Feel free to add some mulch on top to keep in moisture and cut down on weeds.

  • Full sun to partial shade
  • Loamy, moist soil (as found in a marsh)
  • Light to moderate watering


The roots, leaves, and flowers can be used for medicinal purposes, and each requires different harvest times. You likely won’t see flowers until the 2nd year, and it will take a few years before the roots are large enough to be used.

  • Leaves: for fresh use, these can be picked anytime they’re available. If drying, pick just after the plant flowers.
  • Roots: harvest just before the ground freezes in late Fall or early Spring.


Marshmallow is mostly left alone except for the pest rust (a fungal disease). Remove infected leaves and rake under the plant. More natural rust treatments.
