About this list
How was this the best ornamental grasses in zone 6 list ranked?
By how many gardeners actually saved and planted each one in Sow — 16k saves across this list. Each entry is a genus, shown by its most-saved variety, so no single plant appears twice. Nobody paid to appear here, and no nursery sponsors the order.
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 cut back ornamental grasses?
Late winter, before new growth — the standing foliage is winter interest and wildlife cover. Cut cool-season grasses earlier than warm-season ones.
