Though August is often overlooked as a prime sowing month, it offers a great opportunity to plant flowers that bloom quickly or establish for vibrant displays in the seasons ahead. From fast-flowering annuals to hardy perennials, there's a selection suited to many garden conditions and climates.
- Sow certain flowers now for blooms this year or next spring
- Choose from annuals, biennials, and perennials suited to late summer planting
- Use gentle watering and direct sowing for best results
What happened
August is traditionally not seen as a peak time for planting flower seeds, but this late summer month holds untapped potential for gardeners. Whether you want quick blooms or hardy plants that will survive the winter and flower next spring, several great options are available. Some flowers like sweet alyssum and marigolds may bloom this year in warmer areas, while others, including California poppies and black-eyed Susans, will establish well for next year’s show.
Gardeners can sow seeds either directly outdoors or start some indoors, depending on the plant and local climate. Keeping the soil consistently moist after sowing is essential, and using tools like soaker hoses or gentle watering roses can protect delicate seeds. This approach works best with well-prepared soil, lightly covered seeds, and steady care through the remainder of summer.
Why it feels good
Planting flowers in August adds a sense of accomplishment and continued life during a season when many gardeners slow their activities. Watching newly sprouted seedlings take root offers a refreshing reminder that growth and beauty can begin even late in the year. Plus, the prospect of colorful blooms in early spring brings excitement and hope for the coming seasons.
Certain flowers sown in August, such as pot marigolds, also contribute to garden health by attracting pollinators in the fall and serving as companions for vegetables, adding practical benefits alongside their visual appeal. These plants can often be harvested for edible petals, extending enjoyment beyond just looking and smelling the flowers.
What to enjoy or watch next
Look forward to vibrant displays from California poppies in shades ranging from orange to apricot, adding a burst of warmth to gardens that can tolerate drier, poorer soils. Cornflowers will bring classic blues and new color variations to borders and wildflower meadows by late spring, while pot marigolds brighten the current season and provide edible blooms.
Keep an eye on direct sown seeds as they germinate and thin seedlings where needed to encourage strong growth. From here, you can experiment with other late-season sowings or plant indoors to prepare for early flowers. With some care, your August efforts will reward you with a glimmer of color through fall and a splash of brightness next year.
