Botanical Name: Clematis macropetala KLEM-ah-tiss mak-roe-PET-ah-lah Common Name: Downy clematis Genus: Clematis
Downy clematis is a hardy, deciduous early bloomer that can flourish in Zone 4. The species will climb to 10 feet with a little support, and it has bell-shaped, purple-blue, almost columbine-like flowers about 1 to 2 inches, sometimes up to 4 inches in diameter, that mature to fluffy, pinkish seed heads. Blooms appear in spring and early summer, sometimes followed by a second flush in late summer to early autumn
 Noteworthy characteristics: Very hardy. Large, purplish blue flowers and attractive seedheads.
 Care: Usually grown in sun but well suited to shade. Can be grown scrambling through low shrubs or in a tub or basket. Needs little or no pruning. They can be hard pruned to 12 inches, immediately after flowering, if they have outgrown their space. New shoots will bloom the following spring. Keep roots cool and moist and grow in fertile, well-drained, acidic soil with abundant organic matter. Plant with the top of the root ball 3 to 5 inches below the surface and provide strong support.
 Propagation: Root softwood cuttings in spring or semi-ripe cuttings in early summer.
 Problems: Wilt, powdery mildew, rust, fungal spots, and stem cankers are common. Scale insects, whiteflies, earwigs, aphids can occur.

'Nellie Moser' is easy to grow, producing large, flat flowers 6 to 8 inches in diameter with distinctive, gleaming lilac bars on each petal. This clematis blooms from May to late June, with a second, less profuse bloom in mid-August. Planted in a shady spot, the cheery pink-and-mauve-striped blossoms last for weeks instead of days.

'Princess Diana' is a steady bloomer from midsummer into early fall. Its compact habit makes it a good choice for large containers, but it will be just as happy in your perennial border.
