Plant the right nine perennials once and in three years, they will fill a quarter-acre yard. Some will spread by seed, dropping volunteers around your beds. Some will send out underground runners. Some will just keep getting bigger every May until you start dividing pieces off and giving them to your neighbors. The garden center business model relies on you buying replacements every spring. The nine plants in this video ignore that math entirely.
This list is ranked from most polite spreader to most aggressive carpet-former - number one is the plant your grandmother had on the slope by her mailbox in 1982.
Plants in this video are picked for USDA hardiness zones 4 through 8 - covering most of the United States. Check your zone before planting; many regions shifted half a zone warmer under the 2023 USDA Plant Hardiness Zone Map.

If this helped you, drop a comment telling me which of these nine is already in your yard and what year it went in. I read every one.
