About this list
How was this the most popular flowering shrubs in zone 6 list ranked?
A plant must first match the catalog filters named in the title. Each genus is represented and ranked by its most-saved matching variety, so genera with many cultivars do not receive an automatic advantage.
Are all of these hardy in Zone 6?
Yes — every plant on this list is rated for Zone 6. Plants that could not survive a Zone 6 winter were excluded before ranking.
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.
