These dahlias are absolutely stunning. It is my first year growing them, but they are large, strong plants which just keep on producing flowers. My soil is chalk and flint (Thames Valley) so I don't lift dahlias in the winter, and I'm hoping that they'll be fine with a thick blanket of mulch. This year the real stars have been 'Thomas A Edison, with deep magenta-purple flowers 18cm across, 'Jescot Julie', with two-tone flame colours, and 'New Baby', with masses of orange pompoms which last for ages. I recommend these lovely flowers to everyone, but do be aware that they grow so large and lush that you will probably need to support them in some way.

At first I was disappointed with the slow growth, but it was a chilly spring to be fair. Once the plants started to grow they just got better and better. From 8 plants I had loads of vases of flowers for not only myself but family and neighbours right into October. Stunning!

I bought this collection 3 years ago. I garden on very heavy clay soil so I dig up the tubers each year and over winter them in the shed. I have had stunning flowers every year and the tubers are now enormous! I have been very pleased with this collection, they look great in a vase and wonderful in the garden from June to November.

I agree with Gail. This collection would convert just about anyone over to growing dahlias. As a group these produce some show-stopping blooms. I am not far from developing an obsession but unfortunately I am running out of space. These work great in the border or as cut flowers in a vase. Just follow Sarah's advice for wonderful, long-lasting blooms from June through to October/November.

I used to hate dahlias but this collection would convert anyone. The colours bounce off each other, there is an interesting variety of forms and the lovely 'Jescot Julie' with orange on the front of the petals and plum on the back pulls an arrangement of the cut flowers together. This is the first time I have grown dahlias from tubers and may well be the start of an obsession. This collection would make a wonderful present for other novices. Very strongly recommended.
