I have a small garden here in zone 6 in Ohio. I love pastel colors so that is what I have, for the most part. I also garden in small , medium, and large hypertufa troughs. I love sedums and succulents. Thanks for the invite to join in here. Hannah said the more pictures the better, so I hope I am not overdoing it.
My Coreopsis, I think this one is Moonbeam, grows all over. I even have some in urns because it behaves so well.
This circular hypertufa is made from a mold of an old Campfire Pit. It was a large saucer and I used it as a form. It has been wonderful as a container for sedums and alpines.
