Plant Propagation

The seed requires 4 months stratification at 4°c. It is best sown as soon as it is ripe in a cold frame. Stored seed should be sown as early in the year as possible. 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 with a heel, July/August in a frame. Can be difficult[200]. Layering in spring. Easy[200].
