We would like the height to be under 6 inches. Watering is not a problem. It is part shade, and generally protected. Soil conditions because of the light shade, and slight clay composition would not be "well drained". Being zone 5b, we don't care if it is deciduous or evergreen. It will probably get walked on from time to time, but if the plant can not handle that, I can put down a penny paver walkway.
We are only looking to cover an area about 40 - 50 sq feet next to a Koi pond. There are always frogs around, so bugs and slugs shouldn't be a problem.
Ideal bloom would be all summer, and multiple colors (don't ask for much do I !!)
