Clematis ‘Blue Explosion’ is a striking deciduous climber developed by Polish breeder Szczepan Marczyński in 1995. Renowned for its vibrant blooms, this variety produces large, single flowers on old wood in late spring to early summer, followed by single blooms on new growth from midsummer to early autumn. The blossoms, measuring up to 15 cm in diameter, feature a captivating blend of blue petals with pink-flushed tips and yellow anthers, creating a dynamic.
Reaching heights of 2.5 to 3 meters, ‘Blue Explosion’ thrives in full sun to partial shade. While the vine prefers its foliage in sunlight, keeping the roots cool and shaded is essential—mulching or planting low-growing perennials nearby can help achieve this. It grows best in moist, well-drained soils with a neutral to slightly alkaline.
This clematis belongs to pruning group 2 and requires light pruning after the first flowering to encourage new blooms. Its long blooming period and vibrant colours make ‘Blue Explosion’ an excellent choice for trellises, fences, or pergolas, adding vertical interest and attracting pollinators to the garden.
