Planting time was October, when I was here to run the Chicago Marathon. The grass of course had to be dug out, but eventually, we successfully cleared the patch, and the fun began - choosing plants, and planting them.
The initial palette was predictable: Lady's Mantle, Lambs Ears, Clematis, Cranesbill Geranium. Phlox, I believe, a Heuchara, Dianthus. I can hardly remember what all went in at the beginning. Lavender was attempted, twice, but didn't take.
Note the dainty Hosta in the centre, just behind the fountain. Every time I come and the weather is good (so, not at Christmas time!), I work.
It has grown rather larger than expected! Something must be right in that soil. Stay tuned as I mull over this situation ...
