The Clematis x ‘Niobe’ brings an unusually rich color to your garden, like the color of ruby velvet. It is one of the more restrained sized vines (unlike some of the wilder ones like the Autumn clematis) and gives a full show of blooms covering the plant for relatively long period of time. It will create a remarkable feature when used on a trellis or to decorate a pole.
I like its large maroon flowers with their golden boss, especially alongside a group of Echinacea or in the company of Rosa glauca. It has an almost Gothic look to it. Many advise to contrast it with a white or pink climbing rose or other light colored companion, but I like the play of subtle harmonies that such a deep red can inspire.
Penstemon digitalis ‘Husker Red’ would complement the colors with its dusky foliage and whitish blooms; its low growing foliage would also give good ground cover under the clematis vine.
If you are lucky enough, a Cercis canadensis ‘Forest Pansy’ would be a delicious pairing of tones.
I’d also want to try Astrantias and Eupatoriums, since I think they would make subtle contrasts that would highlight the color of the Niobe blooms in just the right way.
Niobe has gained well-earned praise from discerning gardeners. A “type 2” Clematis, it is best pruned in early spring. Cut back about 6 or 8 inches to the nearest pair of strong leaf axil buds; do this about every two to three years.
Another good tip is to mulch the plant well, especially with compost or composted manure.

Clematis: Garden Trellis StarsNiobe Characteristics:

- Grows 8 to 10 feet
- Hardy from zone 4 to 9
- Grow in sun, but shade the roots

- Medium green leaves

‘Niobe’ was raised by Wladyslaw Noll from a plant in Poland, then introduced in 1975 by Jim Fisk, so it is a fairly recent introduction. Not for heirloom gardens.
The variation in flower shade is the effect of how the color changes as the blooms age, particularly with full sun exposure. It doesn’t diminish the beauty at all, and the flowers are very long lasting.
