Sadly I lost the picture, but here goes: It was a pom pom Dahlia with the smallest heads you've ever seen, like not even as big as your little finger. I know it comes in a red, and grows possibly 90cm?
There is a National Collection of Dahlias at Longrock, Penzance in Cornwall ... if you google you'll get their website and phone number. I should think they're your best bet ... good luck

You say it wasn't even the size of your little finger.
Is this the width or length of your little finger.
Was the flower 1 cm across or 6cm?
