If you are looking for something hardy and showy to plant, eryngium is a pretty good bet. It's also known as sea holly, and there are many varieties.
I wish I could tell you what variety this one is. It grows to about 4 feet high and blooms profusely. The flower above is from mid-June. The one below is from yesterday. The flowers are really fascinating to passers-by and to bees.
The leaves and flowers are also quite spiny, so give the plant a good-sized space where it can strut its stuff without being in the way. I trim it back hard in the fall. Supposedly you should divide it in the spring. I will need to do that next year.
