Edible Uses

Edible Parts: Leaves  Root  Shoots
Edible Uses:

Root - raw or cooked[2, 46, 61, 203]. Long, sweet and fleshy[105], when slow roasted they are said to taste like sweet potatoes[183, 207]. They can be used as a flavouring in other foods and can also be chewed raw as a masticatory[177, 183, 212], making an excellent tooth cleaner and also very good for teething children. The root contains 6% glycyrrhizin, a substance that is 50 times sweeter than sugar[183]. The tender young shoots can be eaten raw in the spring[183, 257].

American liquorice was widely employed medicinally by a number of native North American Indian tribes who used it in the treatment of a range of diseases[257]. All parts of the body are medicinal, but the roots are the most active part. This species has properties similar to other liquorices which are widely used medicinally, though this species is rather neglected in modern literature. An infusion of the root is used to speed the delivery of the placenta after childbirth, it is also used to treat coughs, diarrhoea, chest pains, fevers in children, stomach aches etc[207, 257]. It is also used as a wash or poultice on swellings[257]. The chewed root is retained in the mouth as a treatment for toothache and sore throats[207, 257]. The mashed leaves are used as a poultice on sores[207, 257]. The leaves have been placed in the shoes to absorb moisture[257].

Cultivation details

Requires a deep well cultivated fertile moisture-retentive soil for good root production[200]. Prefers a sandy soil with abundant moisture[238]. Slightly alkaline conditions produce the best plants[238]. A very deep-rooted plant, it can be difficult to eradicate once it is established[238]. Unless seed is required, the plant is usually prevented from flowering so that it puts more energy into producing good quality roots[238]. Plants are growing very well at Kew[K]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a runner spreading indefinitely by rhizomes or stolons [1-2]. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [1-2].

Plant Propagation

Pre-soak the seed for 24 hours in warm water and then sow spring or autumn in a greenhouse[200]. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on for their first winter in a greenhouse. Plant out in late spring or early summer when in active growth. Plants are rather slow to grow from seed[238]. Division of the root in spring or autumn. Each division must have at least one growth bud. Autumn divisions can either be replanted immediately or stored in clamps until the spring and then be planted out[200]. It is best to pt up the smaller divisions and grow them on in a cold frame until they are established before planting them out in the spring or summer.

where are the pictures?!?!? they would make it much easier for me to tell what plant you are talking about. This is the one thing missing from your website that would make it excellent.

I live in Florida and would like to grow licorice. Does anyone know where I can get the seeds?

Apparently consistent and/or excessive consumption of wild licorice can lead to health problems. See http://emedicine.medscape.com/article/817578-overview.
