Clematis montana Giant Star White

Common Name:
Clematis 'Giant Star White'

Description:
Clematis montana 'Giant Star White' is a spectacular deciduous climber celebrated for its profusion of large, pure white star-shaped flowers that light up the garden in mid to late spring. This variety is a standout in the Clematis montana group for its oversized blooms and clean, crisp white colour, giving it a striking presence when trained over arches, fences, or walls. The flowers feature four broad petals with a satin-like finish and a centre of pale yellow stamens, offering a fresh and elegant look. The foliage is bronze-tinged when young, maturing to a healthy green that provides a perfect backdrop for the snow-white flowers. Well-suited to Melbourne’s climate, it grows best in well-drained soil with the root area shaded and the top growth reaching into sun or partial shade. Ideal for softening hard structures or adding vertical interest, 'Giant Star White' is fast-growing, hardy, and easy to manage with only light pruning required after flowering.
