Bloomless Liatris

Question

I have white liatris in my garden that never turned white. They grew to be healthy, and I am perplexed as to why it never bloomed. They are in full sun. I watered it enough, even fed it my beautiful compost, but why hasn’t it bloomed for me?

Answer 1

You may need to add more phosphorus to the soil, which helps promote blooming. This article will help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
