Cold weather may be hard on us, but it doesn’t have to rob your garden of its life and color.

If you’re brave enough—and have the right plants—you can create a vibrant winter garden filled with resilient, colorful flowers that bloom even when temperatures drop to 15°F (-9°C) or lower.
Many of these hardy flowers actually thrive in cool weather. Some are seedlings that emerge early before other plants awaken, while others bloom right through snowstorms, offering breathtaking color when everything else looks gray.
