Stored seed requires one month stratification at about 3°c and should be sown as early as possible in the year. Prick out seedlings when large enough to handle and grow on in a cold frame, then plant out into permanent positions in late spring of the following year. Cuttings of half-ripe wood can be taken in July or August and rooted in a frame. Tip layer in July and plant out in autumn. Division can be done in early spring or just before leaf-fall in autumn.
