Dahlia 'Platinum Blonde' (Decorative)
Dahlia ‘Platinum’ is an elegant decorative variety that graces the garden with pristine white blooms, often touched with a whisper of lilac or cream at the heart. Its sophisticated form and clean colour make it a versatile addition to any planting scheme, acting as a palate cleanser amongst brighter colours.
This variety grows into a sturdy bush with broad, lush leaves that provide a dark green backdrop for the luminous flowers. The blooms are waterlily-esque in shape, with broad, slightly cupped petals that create a serene and structured appearance.
Plant in a sunny, open spot in fertile, well-drained soil. It appreciates a position with good air circulation to keep the foliage healthy and free from mildew later in the season.
Water consistently, directing moisture to the base of the plant rather than the foliage. Lift the tubers after the first frost blackens the leaves, clean them off, and store them in a frost-free environment for replanting next spring.
A brilliant choice for sophisticated, neutral borders, ‘Platinum’ brings a sense of calm and purity to the garden, glowing softly in the twilight and mixing effortlessly with all other colours in the vase.
