Buddleia, also known as the butterfly bush, is a fast-growing perennial adored by pollinators. Many varieties are hardy down to zone 5, but a bit of extra care can help them withstand particularly cold snaps.
Winterizing your butterfly bush before inclement weather sets in is super easy and well worth the effort for gardeners in cooler regions – whether you're growing your plant in the ground or in a pot. As Kiersten Rankel of plant-care app Greg highlights, it can help them 'survive freezing temperatures, maintain healthy roots, and produce more abundant blooms' in the spring.
