How to Use Regal Diamantina Clematis in the Landscape

Make every moment count. It's easy to heighten the experience of entryway with a pair of matching arbors placed on either side of a garden gate.

Clematis wraps its leaf stems best around thin supports like wire. Drape wide-mesh netting along the structure, then plant Regal Diamantina Clematis at the base.

Train your pretty vines with tender loving care. Enjoy the process of growing these very special plants.

Create a hidden destination spot at the end of a winding garden path. Use shrubs as walls, and let Diamantina scramble up their length to deliver a delicate flowering focal point.

Sit back, kick your shoes off and appreciate your foresight. Why not add these eye-catching blooms wherever you can?

People are even using Clematis as a groundcover! Plant them in raised beds, or pop them in at the feet of mature evergreens.

Let them grow through a planting of Groundcover Roses. Cool-toned Diamantina looks terrific with peach, white, pink or yellow-colored Roses.

Consider them for perennial container gardens that come back for you year after year. Let them become the "Spiller" at the edge; or use decor to train them up as a "Thriller".

Get ready for the compliments!

#ProPlantTips for Care

Provide a planting site with well-drained soil. Double Clematis love having their leaves in full sun, but their roots in shade.

Install the support for climbers before you plant. Add Nature Hills Root Booster to give the tender roots with life-long symbiotic support to efficiently access micronutrients from the soil.

Wood mulch can also keep the root system cool and moist. Please just ensure it doesn't rest directly against the stems...pull it back a few inches.

Water Regal Diamantina Clematis regularly to keep the soil even moist, without getting too soggy. Container-grown vines need good water and mulch, too!

Prune this variety in early spring, trimming down to live buds. After the first flower flush is finished, simple deadheading produces more flowers later in summer.

That small task is so worth it for repeat flowering! Who can say no to those dramatic blue double flowers?

Treat yourself to Regal Diamantina Clematis this season. It makes a wonderful gift plant, as well!
