I have only this year discovered gaura, and I love them! Plus they seem to do ok with the heat, and just keep on flowering. I have lots of Whirling Butterflies and, to compliment size and colour, lots of Gaudi Pink. I bought them last autumn, and they overwintered well.
I bought them as plants at the end of last summer from The Secret Gardening Club. I have bought more to bulk them out this year from tortworthplants.co.uk and also (arriving today) from eBay.
Jparkers online I bought mine from last autumn. I just left them in the pots all winter and planted them end of March this year. I cut them back to 6cm once frosts had past.
I think you've done really well - you'll have winter interest too with the grasses and other seed heads. Some spring bulbs may be worth thinking about soon - you're probably already doing this!
I think if I can get the rest of turf cleared and finish it to bottom of the garden. I'll be happy doing that. Dug over and manured etc then go from there.
