Just because it comes in a seed packet doesn’t mean it suitable for your garden. These packets are full of noxious, non-native plants. Mr Fothergill’s Wildlife Mixture Wildflower packet would be fine if I planted it in England – every plant listed on the packet is listed as noxious in one of the 50 contiguous states. The Kudzu vine was packaged out of California. Kudzu is a beautiful, great-smelling plant or is a green hell – it all depends on point of view (and how noxious your state weed board views the plant).
Consider gardening with native plants. You may plant an unruly native, but you won’t plant an ecological disaster. Just something to consider when shopping for plants this spring.
