Clematis Brother Stefan® Description

Brother Stefan® clematis (Clematis sp.)  has irresistible large blue flowers that make a striking addition to any landscape.  This easy-to-grow clematis blooms on both old and new wood so there is no wrong way or time to prune this hardy vine - and it blooms much longer than other varieties, too!

This hardy, disease resistant vine climbs around 5-7 feet tall. Use Brother Stefan clematis to dress up a mailbox, trellis, fence, or create the romantic, flower-covered archway of your dreams!   Beautiful when paired with purples, greens, and blacks or any dark color to bring out the sky blue hues. The center of the bloom is accented with a white eye and bright yellow stamens.

How To Grow Clematis

Like other Proven Winners clematis, Brother Stefan is a vigorous, disease resistant selection and needs no fussy pruning.  Just cut it back to 18-24" in late winter or early spring.

The rule to keeping clematis is happy is "head in the sun, feet in the shade" - plant it where the vine and flowers get at least 5 hours of bright sun but the roots remain cool and shaded.  Plant a shallow rooted groundcover such as ajuga or Siberian cypress near the base, or put down a good layer of mulch (avoid heaping it near the crown of the plant, though).  Once it beings to grow in spring, begin training it by angling the stems towards the support structure. Consider using fishing line or bamboo stakes to provide support for the plant, particularly early in the season.

If you've been admiring these gorgeous plants but lack the confidence to try them - or have had bad luck with clematis before - take heart!  You'll find Brother Stefan easy to grow and versatile. It only looks delicate!

Soil: Clematis prefer rich, organic soil (no heavy clay). Do not plant clematis too deeply, and avoid low spots that may cause water to drain toward the base of the plant.
Light: Full sun to part shade. Clematis like to keep their roots cool, so a 2-4 inch layer of mulch is advised once the soil warms up during the hot summer months. To prevent stem rot, be sure to keep the mulch away from the base of the vine.
Water: Medium. Good drainage is a must.
Spacing: 1.5 to 3 feet
Fertilizing: Fertilize your plant once a year in the spring, right after pruning or tidying up.
Winterizing: If you have mulched during the growing season, no special added care is needed.
Maintenance & pruning: Cut the vines back to 18 to 24 inches from the ground in early spring, which ensures the beautiful curtain-like bloom coverage that is prized in clematis.
