Gardeners' Notes:

After experimenting with maybe 10 dianthus varieties, I now plant only two: Frosty Fire and Firewitch. These grow and bloom very well for me. I have not had good luck with any others and eventually shovel pruned them. Frosty Fire is a brilliant magenta color, very eye-catching, but difficult to photograph accurately.

Planted these last spring, and had to transplant them early this summer after they already had a ton of buds on them. I was a little more generous with the watering the first week or two after transplanting, but they have started blooming without issue. Seems like a pretty tough plant. Last year they bloomed all season long with deadheading and VERY littlle watering during our mostly dry, sunny summers. Gets late morning, all afternoon sun here. I would call the color more of a dark hot pink then red. Looks great with my intense dark purple caesar's brother iris blooming in the background.

This plant is located near the foundation of a house which has no guttering. I think that the plant may get too much water. It's not doing as well as I hoped. I only planted it this year, so perhaps next season it will do better.
