Buddleia (butterfly bush) and their flowering ?
I have many buddleia in our garden and most of them flower, varying shades of lilac and purple, which are beautiful. However, I have three bushes that were given to me last spring, they didn't flower that year but grew lots of healthy leaves. I cut them back in this spring expecting flowers this year ( my friend said they were yellow ones . All my other ones are flowering now or dying back but again these newer ones haven't flowered, why is this ?
