One of the best things about wildflowers is their flexibility, but knowing when to plant them can make all the difference in how well they grow.
Spring Planting (March–May)
Spring is a great time to sow wildflower seeds if you want blooms in the same year.
- The soil should be warm enough for seeds to germinate (typically after the last frost).
- Perfect for annuals like black-eyed Susans or blanket flowers, which thrive in warmer soil.
- Spring planting means you’ll usually see flowers by summer or early fall.
Fall Planting (September–November)
Fall is the season to think ahead. Many gardeners love sowing seeds in autumn because it mimics nature’s cycle.
- Seeds rest through the winter and sprout when spring arrives.
- Especially good for perennials like coneflowers, milkweed, or asters that will establish stronger root systems.
- Fall planting also takes advantage of winter moisture, which helps seeds settle in.
Which to Choose?
- If you’re craving quick color, go for spring.
- If you’re patient and want stronger, long-lasting plants, fall planting is worth it.
And honestly, there’s no rule against doing both. Many gardeners scatter seeds in spring and again in fall for layers of blooms that return year after year.
