With white petals and a soft lime centre, Dahlia ‘White Onesta’ captures the imagination through it’s simplicity.

This tender perennial is the ideal choice for a white themed garden to provide a calm and cooling spectacle in the garden.

We recommend planting dahlia tubers, such as ‘White Onesta’, between March and June into fertile, well drained soil 15cm deep and 60cm apart. Position in a sunny location for maximum flowering and impact. After planting, water in well and monitor during the Summer months. Aim for one good soak once a week to the base of the plant.

Some tall and large flowerhead dahlia varieties may need staking for support during the flowering season. Use an all-purpose general plant feed for bigger and brighter blooms. Deadhead regularly to encourage more flowers through till first frosts.
