Clematis
Size: Ranges from 8’-10’ for most, with a few that can get as big as 25'
Exposure: Full to part sun. Ideally, they like sun on their ‘heads’ and cool shade for their ‘feet.’ So-be sure to use mulch at the base to shade roots.
Other Notes: A more controlled, compact vine compared to most. Huge variety of bloom size, bloom time, color, and form.
Note: Clematis may bloom on old wood, new wood, or both depending on variety.
Here's a guide to clematis pruning. If you planted your clematis last season, clip it back to 12" no matter what type it is. If your clematis has been in the ground 2 seasons or more, follow this guide. Pruning types are listed below for the varieties that we carry.
Type 1: Blooms on OLD growth. Prune back immediately after it flowers so that it has time to develop growth for next season's flowers. (these tend to be earlier blooming varieties.
Type 2: Blooms on LAST SEASON'S ripened stems. Typically repeat blooming types. Drastic pruning not recommended with these as you will sacrifice old growth which supplies flowers. Watch for bud swell on the vine and just prune dead parts that are above active growth.
Type 3: Blooms on NEW growth. Prune these vines above new leaf buds in early spring. If it's a particularly vigorous grower, you may be able to prune it back to almost 12" to encourage new growth during the season, and thus more flowers. If your vine is old and established, don't prune into older wood parts.
