Remove the plants from the packaging immediately. Check that the compost is moist and water if necessary.
Clematis can be grown in full sun or partial shade with there roots in shade. Any well drained soil is suitable. The plants will benefit from incorporating well rotted manure or garden compost into the soil. Plant the root ball 5cm (2″) below the soil level to promote basal growth and reduce the risk of attack from the disease Clematis Wilt. In late winter, mulch around the root area with well rotted manure or garden compost avoiding the crown.
In containers the plants will eventually need one that is 35-45cm (13-18″) in diameter. For stability choose a container that is made of stone or a terracotta pot with a wide base, plastic pots are too light and give less winter protection to the roots. A good compost mixture would consist of John Innes number 3 potting compost to which has been added 25% multipurpose compost (by volume) and grit to ensure good drainage. Keep the compost moist and when the plants are in growth apply a balance liquid fertilizer at two week intervals.
Growing up to 200cm (6' 6″) these varieties are suitable for growing up a support in containers or planting against a pergola, trellis or other support. The variety Fleuri is a little shorter growing up to 100cm (39″). Pruning is carried out in early spring cutting all shoots back to strong buds 30cm (12″) above soil level.
These compact miniature varieties can be taken indoors in spring and grown as house plants prior to planting outdoors.

These double flowered clematis can be grown up a support in containers on the patio or
