Marshmallow plant care
Trimming the marshmallow
All parts of the plant (roots, leaves and flowers) can be collected to be eaten.
Wait for the summer to gather them.
Watch out for small bugs!
Although marshmallow is left alone by most critters, it is however highly vulnerable to rust. Also, avoid planting your marshmallow near hollyhock because rust attacks would do double the damage.
The different varieties of marshmallow
The only known species is the one harvested for medicinal purposes. However, a cousin species deserves to be mentioned: hollyhock (Alcea rosea) is also from the mallow family and is grown as an ornamental plant.
Hollyhock has the same medicinal uses as marshmallow. However, its root doesn’t contain as much mucilage. Refreshing drinks can be colored with the purple flowers of hollyhock and its leaves can be eaten like other cooked greens.
