Why didn’t my white Liatris bloom more than once over the summer?

Question

This is the third year for my plant and it started out well, with at least twenty beautiful flower stalks. Once they faded I deadheaded them as instructed. After that the plant didn’t produce any more flower stalks and the foliage didn’t stay rich and green like it has in previous years. The plant gets full sun and we have not had a rainy summer. Any ideas? Thanks.

Answer 1

You are lucky if yours came back a second time in past years. Mine always have produced just one stem of flowers per season.
They may be getting crowded. They benefit from division every few years.
