This guide will guide you through 15 stunning annual flowers that thrive in the sunny conditions of Zone 6, ensuring your garden is both colorful and captivating throughout the growing season.
Understanding Zone 6
Before delving into the beautiful options available, it’s essential to understand what USDA Zone 6 entails. In this zone, winter temperatures can drop to as low as -10°F to 0°F, while summers are warm, averaging between 70°F and 85°F. Therefore, choosing annual flowers that not only love the sun but can also endure the temperature fluctuations of Zone 6 is crucial for a flourishing garden.
Gardening in Zone 6 can be immensely rewarding, especially when you cultivate flowers that can withstand both the harsher winter months and the vibrant summer sun. Let’s explore 15 annual flowers that can transform your sunny garden into a paradise.
