Non -invasive butterfly bush ?
Hello - Are there other Buddleia that are reliably non-invasive, in addition to the Lo and Behold Blue Chip that is being marketed as sterile? I have seen Miss Ruby, Miss Molly and the Flutterby series listed as non invasive in some places, but wanted to check on that information. THanks for your help.
Yes, there are reliably sterile butterfly bushes available on the market now. They tend to be smaller than the straight species and do set some seed, just a much smaller amount than the species.
We have not done our own research on this, so we recommend that you simply use a reliable nursery or website for information.

Glad you are up on the invasives issue. Of course, they are still not a good host plant for butterfly caterpillars and ultimately we can't have butterflies without caterpillars!.
