You get to enjoy up to 5 months of bloom, and the myriad flowers have two totally different looks! In early summer, the old wood produces big semi-double blooms of blue touched with hot pink on the tips; then from midsummer till fall, the new wood bears single blooms of a lovely lavender. From master Polish hybridizer, Szczepan Markzynski. Easy to grow in humusy, well-drained soil, mulch to keep soil cool and moist. In late winter, prune off 10"-12" to a couple of well-developed buds. Clematis 'Blue Explosion'. Nothing beats the spectacular show of a large flowered Clematis in full bloom! It is valued for its ability to scramble up walls, fences, trellises, and even other plants. Plant it with its roots moist and cool, and its leaves in full sun, so mulch heavily or underplant with bushy perennials to keep them happy.
