Description
White Onesta: Decorative Dahlia Tubers
White Onesta is a dreamy dahlia with flawless white open flowers tinted with soft greenish-yellow at the centre. The exquisite blooms measure up to 15cm in diameter and last well in arrangements. Notable for her prolific flowering, she will be covered in blooms from July right through to the first frosts.
Being fairly compact, she makes an ideal specimen plant in containers on a sunny patio or as a mid-sized border plant.

Growing White Onesta Dahlias
Dahlias thrive in deep, fertile soil with good drainage and this compact variety is ideal planted in the middle of a sunny border. She needs staking in windy conditions, preferably with stakes added at planting time so the support will be available when it is needed.
Like other dahlias, she needs to be kept well watered in dry periods, especially if grown in containers. To keep your dahlias flowering abundantly throughout summer and autumn, add a bit of soluble food in the watering can once every couple of weeks.
Planting Companions
Perfect as part of a white garden or pastel scheme, she blends wonderfully with many other mellow dahlias like Gerrie Hoek and Cafe au Lait. For a tranquil white border, combine with drifts of grasses like Pennisetum villosum, the feathertop grass, and soft perennial spires of flower such as white Veronicastrum and Agastache. To create a dramatic container display, pair with a contrasting, vivid dahlia like Summer Flame or El Santo.

Did You Know?
Raised in 2000 by J. J. Warmerdam in the Netherlands, this decorative waterlily dahlia is a delicate white form of the extremely popular pink Onesta, introduced in 1993. The name is Italian for honesty, uprightness and openness, and in 1993 no one could have predicted that the name now sounds like a bad online review.
Waterlily dahlias are a type of decorative full double with open saucer-shaped flowers that resemble the flowers normally found in ponds. They are perfect for cutting and are becoming more popular as a flower for exhibition. They look beautifully elegant displayed in vases or mimicking their namesakes, floating in a shallow bowl of water.
