16 Easy Flowers to Grow from Seed in Spring

What Flower Seeds to Plant in Spring: Easy Flowers to Grow from Seed

Spring is one of the most exciting times to start a flower garden from seed. Whether you are planting a backyard cutting garden, filling containers on a patio, or creating a pollinator-friendly flower bed, many beautiful flowers can be started from seed in spring across the United States.

The best flowers for your garden will depend on your local climate, your USDA growing zone, and your last frost date. Some flower seeds can be sown in early spring while the weather is still cool, while others should be planted after all danger of frost has passed.

In this guide, we’ll share some of the best spring flower seeds to plant in the USA, including easy annual flowers, pollinator favorites, and colorful blooms for beginners.

Before You Plant: Know Your Last Frost Date

Before sowing flower seeds outdoors, check your area’s average last frost date. Cool-season flowers can often be planted before the last frost, while warm-season flowers need warmer soil and should be planted after frost danger has passed.

As a general rule:

Cool-season flowers can be planted in early spring.
Warm-season flowers should be planted in late spring after the soil has warmed.

You can also start many flower seeds indoors 4 to 8 weeks before your last frost date, then transplant seedlings outdoors when conditions are right.

Tips for Growing Flowers from Seed in Spring

Choose the right planting time for each flower. Cool-season flowers can go in earlier, while warm-season flowers need frost-free weather.

Prepare your soil before sowing. Remove weeds, loosen the top layer of soil, and mix in compost if needed.

Follow seed packet instructions. Some seeds need light to germinate, while others should be covered with soil.

Keep soil moist during germination. Seeds need consistent moisture, but the soil should not be soggy.

Thin seedlings when needed. Crowded plants compete for light, water, and nutrients.

Plant in the right light conditions. Most flowering annuals need full sun, but some, like impatiens and violas, can handle partial shade.
