Clematis Piilu is a classic large-flowered clematis chosen for showy blooms and repeat flowering. Group 2 clematis give their main display on older stems in late spring/early summer and often flower again later, making them ideal for high-impact vertical planting in a premium garden.
Compact, container-friendly clematis with large blooms often showing distinctive striping and strong repeat flowering potential. Expect a strong early-season flush, frequently followed by a later repeat display when the plant is happy.
Group 2: in late winter/early spring, remove dead or weak stems, then trim remaining stems back to the highest pair of strong buds. Avoid hard pruning unless you accept fewer early flowers.
Plant slightly deeper than pot level to encourage strong new shoots from below ground. Water well and mulch. Provide a trellis or wires and gently tie in young growth until it starts to twine.
Typically a moderate to vigorous climber depending on variety, ideal for trellis, arches and pergolas, or for combining with roses and shrubs.
