Gardeners' Notes:

Started these from seed in containers (in May, Zone 5a). I expected them to struggle, but in Early August I have large healthy plants covered with purple/lavender blooms. They are quite vigorous and even seem to crowd out some of their container neighbors.
They don't smell as good as I expected, given all the hype. Still a pretty plant which fills and spills. I may have to clip them back or they'll choke out my dianthus :)
