Marsh Mallow (Althaea Officinalis) - Every herb garden needs to have this versatile perennial! It is highly regarded as a beneficial medicinal herb and has been widely used for the last 2000 years in both foods and in medicines. It is native to Europe but can be found growing in many places around the world. It is easy to grow from Marsh Mallow seeds, and it also makes a lovely flowering display as well as having therapeutic benefits.

Both the roots and the leaves have a slimy substance called mucilage. When the mucilage is mixed with water, it creates a viscous gel that coats and sooths irritated mucous membranes. It is used for coughs, colds, sore throats, stomach and intestinal conditions. It is also very beneficial when applied to skin abrasions or insect bites. The Marshmallow root is yellow-white and sweet. It is similar in taste to a parsnip. The roots can be harvested in the fall for drying.

Plant history

The history of our modern day sugary marshmallow goes back to this herb plant. The gummy substance, mucilage, was actually the thickening ingredient in a dessert made from egg whites.

How to grow

How To Grow Marsh Mallow From Seed: Marshmallow herb plants prefer moist soils. Some gardeners recommend a fall planting so that the cold temperatures aid in the germination of the Marshmallow herb seeds.

If starting the Marshmallow seeds indoors, place the herb seeds in moistened peat moss, and place the peat moss/seed mixture in the refrigerator for 4 to 6 weeks. After that cold treatment, sow the herb seeds in small pots. Once established, the Marsh Mallow plant is known to self-seed but not in an aggressive way.
