Edible parts of Hop Tree:

Fruit. A very bitter flavour, though it is eaten by young children. The fruit is also used as a hop substitute when making beer and it is added to yeast to make it rise more quickly when making bread. The fruit is produced abundantly in Britain, though very little of it is fertile. The fruit is very thin and about 25mm long.

Other uses of the herb:

Sometimes used as a hedge plant in N. America. Wood - hard, heavy, close grained. It weighs 51lb per cubic foot but the tree does not grow large enough for commercial exploitation.

Propagation of Hop Tree:

Seed - best sown as soon as it is ripe in a cold frame. Stored seed requires 3 months cold stratification at 5C and should be sown as early as possible in the year. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Very little of the seed produced in Britain is viable. Cuttings of half-ripe wood, July/August in a frame. Layering.
