Echinacea Yellow My Darling - Tip: Choose plants that are hardy, avoiding plants that are less hardy than your zone.If you live in a zone 4, but can get away with growing perennials that are only hardy to zone 5 – this is not the best time to plant. These perennials need a full growing season for the best chance to overwinter, particularly as a young plant. In fact, it is safest to plant perennials that are one zone hardier than yours (planting a zone 3 perennial if you live in zone 4).
