Propagation

• Graine - Semez au printemps sous un chassis .
• Prick out the seedlings into individual pots when they are large enough to handle - if you want to produce clumps more quickly then put three plants in each pot .
• Cultivez les sous serre durant au moins leur premier hiver et plantez les à leur position définitive au printemps, une fois qu'elles poussent vigoureusement et sont suffisamment développées .
• Division au printemps .
• The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions .
