Reliable white with a classic decorative form. It's one of the better white dahlias for the garden and exhibitions. I enjoy growing it. Released in 1979.

We've been growing dahlias for many years. Dahlias are tuberous rooted perennials with pinnately divided leaves and showy flower heads, double in many cultivars, in summer and autumn. 

When we talk about giants, we talk about the size of the flower, which is usually the size of a dinner plate. I don't mean that the plant itself is huge. Usually, the plants are about 2-3ft tall and need staking. The giants would be one of our most popular varieties and surprisingly weather-resistant. The only thing that can knock them back is strong winds in late autumn. Sheltered spots for the giants are best.

Dahlias require a fertile, moist but well-drained soil, and a sunny, sheltered spot. The taller varieties need staking. In autumn, dig up the tubers and overwinter them in a frost-free place, such as a greenhouse or a shed. Bring them back into growth in early April, then plant out in the garden from May onwards.

Shipping Note :

Our Dahlias are all unique varieties propagated here are the nursery. We ship them as growing plants typically 10 to 15cm high, not as tubers. This way you are sure that your plants have the  best opportunity to grow and be successful.  Orders placed for Dahlias are only shipped/available starting in May as we protect them for you from frost until then.

It is important to only plant Dahlias when all chances of frost have passed.  When you place your order you will receive an email to confirm that we have received your order. You will then get a further email when your plants are either shipped or ready to collect from the Garden centre depending on what shipping option you picked at checkout time.
