Interesting twisted flowers in a fine colour, and very floriferous for the past couple of months, with many flowers out and still to come at the end of October. I've just ordered another to complement it next season.

Grower: A. Street(Great Britain). Introduced in 2000. A dahlia with very small brownish red flowers..Over here in Netherlands it is chosen by readers of an outstanding gardening magazine (Onze Eigen Tuin) to be the most favoured dahlia to spite of all the many dahlias that will grow big, bigger, biggest..
In my garden it did'nt flower as I've expected. It had a very leggy habit and it looked messy. This in spite of all the many small flowers. We had a very rainy season though.

It adds a splash of rich colour to the autumn garden, but the ragged flowers may not be attractive to everyone. Welcome as a novelty. My impression may improve once the plant has bulked up as it is only in its first season. It appears to have many flowers still to come as we near the end of September
