| I am a student at Michigan State University and I am doing a paper on the butterfly Bush and I was wondering if you could tell me the the optimum soil pH for the plant? It would be greatly appreciated!! Thank you, Valerie |
| This plant is highly adaptable and does not require a specific pH to do well in the sense that some plants might require an acid or alkaline soil. Doing a quick search I am unable to locate any reference indicating an "optimum". |
