6a. Flowers every year, perennial (windy rural)
Once established, many plants that flower every year (perennials) can largely be left to do their own thing. They annually manage a good floral season without the need to 'deadhead' (remove spent blooms). In most cases they eventually form large clumps. You can choose to divide these or just leave them alone!
