'Diamond Ball' Clematis

Clematis ‘Diamond Ball’ is a deciduous climbing vine with rounded, double flowers in cool white and icy blue. The prolific flowers measure about 4–5 inches across and appear from June through August on both old and new stems. ## Flowers and siting The [Proven Winners cultivar profile](https://www.provenwinners.com/plants/clematis/diamond-ball-clematis) lists a mature height of 5–6 feet, a spread of 2–3 feet, zones 4–9, and part-sun to sunny exposure. Its compact growth suits a trellis near a mixed border or a large container. The [Canadian cultivar record](https://active.inspection.gc.ca/english/plaveg/pbrpov/cropreport/cl/app00008606e.shtml) describes pale blue sepals with a white central bar and confirms the breeder and denomination. ## Support Set a sturdy trellis or fence where the leafy vine receives sun and the root zone can remain cool and shaded. Mulch or nearby low plants can shade the base. ## Maintenance This selection flowers on old and new wood. In early spring, prune to about 18 inches according to the [cultivar growing notes](https://springmeadownursery.com/plantfinder/diamond-ball-15440). Keep the soil moist but well drained.
