Zone 6a
Zone 6a is the predominant planting zone in Youngstown, covering most neighborhoods including Downtown, North Side, South Side, and West Side. Zone 6a is suitable for cold-hardy vegetables like Broccoli (Brassica oleracea var. italica) and Kale (Brassica oleracea var. acephala), along with ornamentals plants such as Hosta (Hosta spp.) and Purple Coneflower (Echinacea purpurea). Fruit trees like Apple (Malus domestica) thrive here due to their tolerance for moderate winter freezes.
