I think I’ve said it before, but when it comes to garden plants, one of the biggest bangs for your buck is definitely Dianthans.
I bought them a couple years back, and they were labels as annuals, but they came back the next year, and the year after. In truth, they are a short-lived perennial (usually three-four years), but as they are often sold as annuals, you can get usually get them in four-packs for just a few dollars (at least around here).
And once they get established, boy do they bloom!
Just look at those flowers! They come in a huge variety of patterns and shades. And They bloom like crazy, all summer long. They love sun or shade. You can’t get any better than that!
