Propagation

• Graine - le mieux est de semer dès qu'elles sont mûres sous un chassis [111].
• The seed can be stratified and sown in spring but will then be slow to germinate [133].
• When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter .

• Division - best done in spring but it can also be done in autumn [1, 111].
• Another report says that division is best carried out in the autumn or late winter because the plants come into growth very early in the year [233].
