I've planted two Butterfly Bushes in my garden and haven't seen any seedlings sprout, so I was surprised to find out they're considered noxious weeds here in Connecticut. I've only spotted them in gardens and never while hiking. I know in places like England they can spread like crazy. Are there specific varieties that don't have this problem? I've come across conflicting information online, with some sites selling them claiming they aren't invasive. What's the deal?

When it comes to Butterfly Bushes, some varieties are marketed as sterile, meaning they won't produce seeds. I’ve had a few in my yard without them spreading like crazy. However, I did inherit a trumpet vine from previous owners, and that one is a nightmare! It just won't die! So you might just need to choose carefully when picking types of Butterfly Bushes.
It can vary a lot! There are over 100 different varieties of Butterfly Bushes. Some do spread and can be invasive, while others are more controlled and don't escape into the wild. It’s important to research specific types before planting. I’ve had issues with certain plants, but some of mine have been just fine!

Exactly! People often group all Butterfly Bushes as invasive, but that’s not the case for every variety. Just make sure to get info from reliable sources!
