Hi there, I'm hoping some experienced gardeners may have some ideas for a bare spot in my garden. This is in a raised area, surrounding my fountain, with lots of clay in the soil. Full sun. You can see the dianthus coming up around part of it (though not sure if those will live beyond this year; I put them in last year assuming they were annuals but they have come back strong), but I've still got a lot of empty space (on one side it's about 3' x 3' and the other just a bit smaller).
I'm open to annuals or perennials (zone 5), and most of all want something that has a long season and is interesting to look at and is low maintenance (watering is about as much maintenance as I like.)
