Marshmallow is a herbaceous perennial plant that dies in the autumn and again emerges in the spring. Its stem grows upright, sparsely branched, to a height of 3 to 4 ft. The oval or more roundish shaped leaves grown on a small petiole, attains a length of 2 to 3 inches and a breadth of 1 and a half inches. Leaves grow thick with toothed margin in 3 to 5 lobes and the stellate hair covering both sides of the leaves gives it a velvety texture. The flowers grow in panicles and are often pale or reddish white color that looks similar to the flowers of the common mallow herb but are comparatively smaller. All the parts, especially the roots consist of mild mucilage.


Marshmallow prefers salty soil with a moist environment; hence it can be seen in most parts of Europe, north eastern areas of North America and some parts of Asia. It can be seen growing in damp meadows, brackish marshes, around the coastal areas, near the banks of rivers, etc., where the soil is always moist, and in the surroundings of ditches.


Marshmallow can adjust in all types of soils like light, medium and clay, but the only condition is the soil should be moist and pH value should be high as it can thrive in saline, acidic or neutral soil. It grows well in black colored, extremely fertile soil called as black-dirt, soil and it yields better when grown in such mechanically composed soil.



Planting by the seedling method is a bit tricky, so patience is needed. It takes longer for the seeds to germinate; hence it is preferable to sow seeds indoor about 10 to 12 weeks before the end of frost. Getting the seeds stratified will help in the germination process. Seeds can be sown in a light soil pot fertilized with good organic compost. Care must be taken to keep the soil moist all the time, with enough sunlight. In the beginning, all the seeds can be sown in a single pot, and as they emerge, they can be placed into individual pots. Transplanting should be done only after it grows large enough and a distance of 3 feet must be kept. Plants should be supplied with a good amount of water; hence using a soaker hose near the base path will be excellent. It should be used for at least an hour every day, especially during the hot climate.
