Edible Uses:

Fruit - fresh or preserved[1, 22, 61]. Somewhat like a mulberry[183]. The firm fruit is relatively tasteless, when soft-ripe it is sub-acid to sweet and some forms can be quite delicious[46, 105, 109, 151, 183]. It contains lots of large seeds[151]. The fruit is about 25mm in diameter[200]. Leaves - a famine food[179].
Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Antiperiodic;  Galactogogue;  Ophthalmic;  Women's complaints.

An infusion of the wood is used to treat sore or weak eyes[178, 218]. The inner bark and the wood are used in the treatment of malaria, debility and menorrhagia[178, 218]. The root is galactogogue and is also used in the treatment of amenorrhoea[218]. The plant is used to eliminate blood stasis and stimulate the circulation in cancer of the alimentary system, blood and lungs[218].


Other Uses
Dye;  Fibre;  Wood.

A yellow dye is obtained from the wood[178]. The bark fibers are used for making paper[266]. Wood - finely grained. Used for utensils[178].
Cultivation details
Prefers a warm well-drained fertile loam[1, 188]. Requires a sunny position[188]. A very hardy plant[1]. The leaves are a food source for silk-worms[1, 11]. Probably only the male tree is in cultivation in Britain, though at least one selected female form is being grown in N. America[183]. Both male and female plants normally need to be grown if fruit or seed is required but male trees occasionally produce a few small fruits[183].
Seed - best sown as soon as it is ripe in a cold frame[188]. Sow stored seed in early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in a frame[188, K]. Cuttings of mature wood, November in a sandy soil in a frame[1].

I found the fruit to be rather tasteless on it's own but very useful when adding colour to jellies, making it pinkish, like quince.

This is a very invasive plant it roots spread EVERYWHERE. You can't contain it it grows under the sidewalk under the street to the neighbor's yard. I have been digging it up for 25 years and can't get rid of it it entangles itself in the roots of azaleas and other shrubs.
