Clematis 'Isago'

Semi-double to single flowers are produced in late summer and early fall.

Common Name: Clematis

This elegant reblooming Clematis produces large 4-5”, fluffy, white, double flowers in May and June. Semi-double to single blossoms follow in August and September.

‘Isago’ is a member of pruning group 2 and should only be pruned lightly. It is especially striking when planted in a sheltered but sunny location against a dark backdrop.

A member of:
Group 2—Early to midseason flowering cultivars and rebloomers
These varieties begin to bloom in early summer, with the first flush of flowers appearing on the previous year's growth. This is followed by a second flush flowers appearing on the new growth. These flowers will likely be smaller than the first ones and flowers that were double the first time may be single the second time.

The time to prune this group is in late winter or early spring. Dead and weak shoots should be removed and the remaining shoots cut back to 6-9 inches above a couple of well-developed buds.

Clematis can be grown in full sun or light shade, but its base and roots must be completely shaded. You may need to plant a small shrub or large perennial directly in front of its rootball to keep it cool and shaded. A thick layer of mulch will also help to keep the soil moist. This vine prefers to be grown in moist, well-drained, slightly alkaline soil. Adding lime to the soil will help to provide these conditions.

When planting clematis, it is important to plant it 3" deeper than it was in the original pot. Bury the first set of entire leaves to encourage the production of strong shoots from below soil level and to discourage clematis wilt.
