Late Summer Color Annual Flowers to Keep Your Garden Blooming Through Fall

As midsummer rolls into late summer, many gardens begin to fade. But with the right plants, your flower beds can stay vibrant and full of life well into fall. Here are 5 of our favorite annual flowers to plant now for an extended season of color.

🌼 1. Cosmos

Cosmos are heat-loving and drought-tolerant, blooming from mid-summer to first frost. Their daisy-like flowers flutter on tall, feathery stems and come in pink, white, and deep burgundy. Deadhead regularly for nonstop blooms.

🛒 Pair them with our bulk cosmos seeds for large displays.

🌸 2. Zinnias

Zinnias thrive in the heat and put out bold, vibrant flowers right up to frost. They're excellent for cut arrangements and attract butterflies in droves.

🛒 Try bold mixes like Magellan or Cut & Come Again.

🌿 3. Marigolds

From dwarf French types to tall African varieties, marigolds are champions of late-season blooming. Their warm gold, orange, and red tones scream fall — plus they repel pests naturally.

🛒 Great for veggie garden borders and planters.

🌺 4. Celosia

Add texture with celosia’s flame-like plumes or cockscomb blooms. These vibrant flowers hold up well in the heat and bring unusual shapes and colors to your garden.

🌷 5. Salvia

A magnet for hummingbirds and pollinators, salvias offer spikes of blue, purple, or red flowers late into the season. Most varieties thrive in full sun and don’t mind dry spells.

🌞 Tips for Late Summer Planting:

• Keep new seedlings well-watered for the first 1–2 weeks.

• Add mulch to retain moisture and reduce weeds.

• Fertilize lightly with a bloom booster once established.

Even a small patch of late-blooming annuals can extend your garden's show and support pollinators into fall. Happy planting!
