Late summer is a vibrant time in the garden, especially in Zone 5, where the growing season begins to wind down. Choosing the right annual flowers can ensure your garden remains colorful and lively until the first frost. Here are the top five annual flowers that thrive in late summer and provide stunning color in Zone 5 gardens.
1. Zinnias
Zinnias are a gardener’s favorite for their bright, bold colors and easy care. They bloom profusely from mid-summer to fall, making them perfect for late-season color. Zinnias come in a variety of shades including red, pink, orange, yellow, and white. They thrive in full sun and well-drained soil, and their long-lasting blooms attract butterflies.
2. Marigolds
Marigolds are hardy annuals that add warmth and vibrancy to late summer gardens. Their golden, orange, and yellow hues complement other summer flowers beautifully. Marigolds are also known for their pest-repelling properties, making them a practical choice for vegetable gardens as well. They prefer full sun and can tolerate poorer soils.
3. Cosmos
Cosmos produce delicate, daisy-like flowers in shades of pink, white, and deep red. They are tall, airy plants that sway gracefully in the breeze, adding movement to the garden. Cosmos bloom from mid-summer through fall and attract pollinators like bees and butterflies. They prefer full sun and well-drained soil.
4. Sunflowers
While often associated with summer, certain dwarf sunflower varieties can thrive into late summer and early fall. Their large, cheerful yellow blooms are a striking addition to any garden. Sunflowers prefer full sun and well-drained soil. They are also excellent for attracting birds and pollinators.
5. Cleome (Spider Flower)
Cleome, or spider flower, offers unique, spiky blooms in shades of pink, white, and purple. Its tall, airy stems add height and texture to the garden. Cleome blooms from mid-summer to fall and is drought-tolerant once established. It prefers full sun and can handle a variety of soil conditions.
