Is that late for you? I know that I would even struggle to get a Canna to flowering size here. You seem to have quite a few there in amongst the japanese anemones and it's a great contrast in colour and leaf.
I just love the way the leaves glow.
Lovely - great pic :) Mine are in pots and never as successful as I'd like!
The flower and leaf colour combine beautifully. An interesting idea for the late summer. Christina
