What's plant to use that is similar to perfoliate alexanders?
I determined not to have pom pom envy next year. After having read GW the suggestion was to have perfoliate alexanders with them. But I can only get seeds, and I'm not confident about them being sown direct.
So I'm after other suggestions for a yellowy flowered plant with acid green foliage to show off purple sensations next Spring.
Any suggestions would be most welcomed.
