Pot up plants and grow them on in frost free conditions until all risk of frost has passed. When plants are well grown, gradually acclimatise them to outdoor conditions over 7 to 10 days before transplanting into borders and containers. The herbaceous perennials in this collection can be grown in any moist, fertile soil, in sun or semi shade. Work some compost or general fertiliser into the top 20cm of the soil prior to planting.
In autumn, cut back the old foliage to ground level and apply a mulch of well rotted manure or garden compost to the base of the plants. Lift and divide overcrowded clumps of perennials in autumn to maintain their vigour.
