Deep blue flowers display silvery-blue tips.
Clematis are grouped into three different categories for pruning and maintenance:
Group 2: Large flowering hybrids (mid-June and rebloomers) - bloom on short stems from the previous years growth, often reblooming on the new growth in late summer. Prune in early spring: remove all dead and weak stems, on healthy stems, prune weak tips back to plump green buds. If plants are pruned after the first flush of flower, they will have better branching, but the second flush of flowers will be lost.
Clematis grow best in a rich, moist to average, well-drained soil, in full sun. Protection from intense afternoon sun is beneficial. Large flowering bi-colours, reds and blues, may fade quickly if planted in direct sun. Roots need a cool environment to thrive; it is recommended planting a ground cover or shallow rooted perennial to shade the roots; mulching is suggested. Plant the crown 3-5 cm below the soil's surface. Clematis are slow to establish and initially need to be tied to a trellis or fence to begin climbing.
