Edible Uses

Edible Parts: Fruit Leaves
Edible Uses:

Fruit - raw or dried for later use[118, 177]. The fruits are about the size of small peas and are produced in terminal clusters on the plants, they are not regarded very highly[256]. North American Indian children would eat the raw unripe green berries straight from the plant[256]. Adults would usually harvest the green berries and then store them in water until they turned red and were soft[256]. Alternatively they would dry the green berries and then boil them for a few minutes[256]. Young leaves - cooked[177].

Infertility Ophthalmic Poultice TB

A poultice made of the whole or the mashed leaves has been applied to boils, burns, cuts and wounds[257]. The fruit has been used as a good medicine in the treatment of tuberculosis[257]. The root has been chewed in order to correct sterility[257]. (This probably means to restore fertility[K]) An infusion of the pounded roots has been used as a wash for sore eyes, whilst the chewed roots have been used as a poultice on the eyes[257].

Plant Propagation

Seed - best sown quite thinly it as soon as it is ripe in a cold frame, it should germinate in the spring. Stored seed should be sown in late winter in a cold frame, it might take 18 months to germinate. Allow the seedlings to grow on in the pot for their first year, giving liquid feeds as necessary to ensure that they do not go hungry. Divide the plants into individual pots once they have died down in late summer. Grow them on in pots for another year or more until large enough to plant out[K]. Division as new growth commences in the spring. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
