Bog Sage, (BUT it does NOT need to be grown in a bog!) features truly blue flowers…plus it blooms all summer long. It is attractive to all pollinators, and deer resistant. Height will depend on how moist your soil is, but expect 3′ plants nonetheless (up to 5′). Reports on winter hardiness vary, but some of our zone 6B customers say it comes back for them!
Hardiness zones: (6B) 7-10
