As it's been such a mild autumn so far, one of our very late flowering Dahlias actually had the chance to flower this year.

This plant was given to us a few years ago by a friend, which he originally sourced from Crug Farm. It has been reliably hardy for him, with his location much colder than ours, and as expected has been reliably hardy so for us too. It is deciduous in the colder months and sprouts back from the ground again in the spring. I tried to overwinter one in a pot before, inside a heated greenhouse wondering if it will remain evergreen, but it still went dormant regardless.
It's one of the most statuesque Dahlias you can grow, and I highly recommend if you want a foliage plant that looks majestic in just one season. And like this year you might get an autumn bonus and get it to flower too!
