Whether you deem the ninth month late summer or early fall, one thing's for sure—September light is magical! Take advantage of the sun's lower angle, allowing it to pass through mesmerizing leaves and bounce off dazzling blooms. Our picks: 'Red Giant' mustard, 'Bonanza Harmony' French marigolds, and 'Angelina' sedums. When backlit, the ribs and veins of 'Red Giant' glow white to chartreuse, contrasting with its deep maroon, puckered foliage. We love the 'Bonanza Harmony' marigold for its intense shades of red punctuated by yellow centers. Tie it all together by planting the edge of the container with 'Angelina' sedums. Fill the pot with a high-quality, premoistened potting soil that contains fertilizer. Water your container in the morning, when the soil is slightly dry to the touch. Encourage new growth by snipping away yellowing leaves at the base of the mustard, and coax new buds by pinching off spent marigold blooms.
