Flowering Shrubs in Zone 6

What are the best flowering shrubs plants for Zone 6?

The 24 above are the most-saved flowering shrubs plants that are also rated hardy through Zone 6. Ranking by real gardeners — not by catalog marketing — surfaces the ones gardeners keep coming back to.

Will these survive Zone 6 winters?

Every plant listed here is rated for Zone 6, where winter lows reach -10°F to 0°F. Site conditions still matter: drainage, wind exposure, and a good layer of mulch make the difference between a rated-hardy plant and a happy one.

When do I prune flowering shrubs?

It depends on where they bloom: old-wood bloomers (lilac, oakleaf hydrangea) get pruned right after flowering; new-wood bloomers (panicle hydrangea, butterfly bush) in late winter. Pruning at the wrong time is the #1 reason shrubs skip a year of bloom.
