Gee Bob that is really nice. Love the colour. Tried growing these last year. They grew & flowered but didn't get very tall. Maybe I didn't start them early enough. Of course it could be that they don't grow in my zone. Might try them in containers next year. Good photo.
Thanks Lenjo & broots.
These have done well here, zone 7b, but they are in large pots and get watered then moved around by hand. We'll see how well they do next season. Also, they seem to sparkle and fade and sparkle again depending on (hot) weather.
