Q. Is butterfly bush good or bad for the garden?
Thank you for your question in regards to the butterfly bush controversy. Well, according to the NABA North American Butterfly Association, Buddleja davidii is a helpful plant, although not a native, comprises over 140 species of flowering plants endemic to Asia, Africa, and the Americas. Butterfly bush is helpful to the butterflies throughout the season, although can be invasive, but there’s more to it, and how it is maintained. Different native plants that provide for the butterflies may only do so for a two-week period. Growing different natives is good idea, but still each provide for different two-week periods in the growing season. See complete information below:
“http://libguides.nybg.org/butterflygardensButterflies will visit your garden if there is an abundance of nectar plants and certain, specific, larval-host plants.” More from our guides at NYBG called libguides, researched in our world famous Mertz library. http://libguides.nybg.org/butterflygardens
Thank you for being a caring gardener!
Hope this helps.
