Plant Features

Clematis Diamantina features lavish, violet-blue double blooms that unfurl like layered jewels, each lasting up to 4 weeks. It first bursts into bloom in late spring and then graces the garden with repeat flowers later in the season. Compact and vigorous, it thrives in moist soil and dappled light, making it an excellent choice for containers or vertical accents.

Growing Guide
When to Plant	Plant when the risk of frost has passed or during any frost-free period when air temperatures are consistently above 45°F. Ensure the root zone stays cool while the vines reach for sunlight
Soil Setup	Thrives in loose, well-draining soil with a pH of 6.0–7.0
Watering Tips	Soak in-ground plants deeply 1–2 times weekly (unless rain suffices), keep leaves dry if evening; keep containers moist, up to twice daily in heat
Feeding Your Plants	Apply a balanced, slow-release fertilizer at planting. Follow up with a low-nitrogen fertilizer (10-30-20) every 4 weeks during the growing season to promote strong flowering
Shaping & Support	Provide a trellis, arbor, or other sturdy support for climbing. Minimal shaping is needed, but light pruning can be done as needed. Can be pruned using Group 2 methods
Pest & Disease Control	Generally pest-free, but good airflow and proper care help maintain plant health
Temperature Tolerance	Cold-hardy and can withstand temperatures down to -30°F

Lovely climber

My diamantina plant added a nice pop of color to my trellis. It’s been bloomed well in the first year and seems pretty easy to care for so far. Happy with it!
