There’s something magical about growing flowers from seed. Watching tiny sprouts push through the soil and transform into beautiful blooms is one of the most rewarding parts of gardening!

12 Flowers That Grow Easily from Seed
1. Sunflowers (Helianthus annuus)
If you want an easy, high-impact flower, sunflowers are the way to go! Just plant the seeds in full sun, keep them watered, and watch them grow—sometimes towering over your head! Plus, they’re a great way to attract pollinators and provide food for birds.
Best places to sow: Sunflowers thrive in garden beds, along fences, or as a backdrop for smaller flowers. They do best in full sun and well-drained soil.
Growing tips: Sow seeds 1 inch deep after the last frost. Space them at least 6 inches apart for dwarf varieties and 12+ inches for taller types. Water regularly until established.
2. Zinnias (Zinnia elegans)
Zinnias are the ultimate beginner-friendly flower. They sprout quickly, bloom in a rainbow of colors, and love warm weather. The more you cut them, the more they bloom!
Best places to sow: Zinnias love full sun and grow well in garden beds, containers, and borders. They need well-drained soil to prevent mildew.
Growing tips: Sow seeds in well-drained soil after the danger of frost has passed. Thin seedlings to about 8-12 inches apart. Water at the base to keep foliage dry and prevent disease.
3. Cosmos (Cosmos bipinnatus)
These delicate, daisy-like flowers thrive on neglect. They love full sun and can handle poor soil. Once they start blooming, they keep going until frost!
Best places to sow: Cosmos do well in flower beds, along pathways, or in wildflower gardens. They prefer full sun and well-drained, even slightly sandy soil.
Growing tips: Scatter seeds over prepared soil and lightly press them in—no need to cover them. Water regularly until they sprout, then water sparingly as they are drought-tolerant.
4. Marigolds (Tagetes spp.)
Marigolds are tough, cheerful flowers that help repel garden pests. They’re perfect for vegetable gardens and borders, and they bloom nonstop with little effort.
Best places to sow: Marigolds thrive in vegetable gardens, flower borders, and containers. They love full sun and tolerate a range of soils.
Growing tips: Sow seeds directly in full sun after the last frost. Keep the soil moist until they sprout. Deadhead spent blooms to encourage continuous flowering.
5. California Poppies (Eschscholzia californica)
These golden beauties thrive in dry, sandy soil and are virtually maintenance-free. They reseed themselves, so you’ll likely get new flowers year after year!
Best places to sow: California poppies are perfect for wildflower meadows, rock gardens, and borders. They thrive in full sun and dry, well-draining soil.
Growing tips: Sow seeds in early spring or fall. They don’t like to be transplanted, so direct sowing is best. Avoid overwatering, as they prefer dry conditions.
6. Nasturtiums (Tropaeolum majus)
Nasturtiums are beautiful, edible flowers with a peppery flavor. They’re great for hanging baskets, garden borders, and even as ground cover.
Best places to sow: Nasturtiums grow well in garden beds, containers, and trailing over walls. They do best in full sun but tolerate partial shade.
Growing tips: Soak seeds overnight before planting to help with germination. Sow in well-drained soil and full sun. Avoid rich soil, as too much fertility reduces blooming.
7. Alyssum (Lobularia maritima)
This low-growing flower forms a carpet of tiny, fragrant blooms that attract pollinators. It’s perfect for edging, containers, and filling in garden gaps.
Best places to sow: Alyssum is ideal for garden borders, rock gardens, and container plantings. It thrives in full sun to partial shade and well-drained soil.
Growing tips: Sow directly in early spring. Keep the soil moist until germination. Trim back after the first flush of blooms to encourage reblooming.
8. Bachelor’s Buttons (Centaurea cyanus)
Also known as cornflowers, these charming blue flowers are super easy to grow and make wonderful cut flowers.
Best places to sow: Bachelor’s buttons do well in wildflower gardens, cottage gardens, and along fences. They thrive in full sun and well-drained soil.
Growing tips: Scatter seeds in early spring. They tolerate cooler temperatures, so they can even be planted before the last frost. Deadhead spent blooms for continuous flowering.
9. Sweet Peas (Lathyrus odoratus)
Sweet peas are a fragrant and delicate climbing flower that thrives in cooler weather. They add charm to trellises and fences with their beautiful pastel blooms.
Best places to sow: Sweet peas grow best along fences, trellises, and garden edges. They prefer full sun and well-drained soil with good moisture.
Growing tips: Sow seeds in early spring as soon as the soil can be worked. Soak seeds overnight before planting to aid germination. Provide support for climbing varieties.

Morning glories are fast-growing vines with stunning trumpet-shaped flowers that open in the morning sun. They are perfect for covering fences and trellises.
Best places to sow: Morning glories love full sun and grow well along fences, arbors, and trellises. They do best in well-drained soil.
Growing tips: Sow seeds after the last frost. Soak seeds overnight before planting to speed up germination. Provide support for vines to climb.

These bright yellow flowers are a favorite of pollinators and add a wildflower look to any garden. They’re drought-tolerant and easy to grow. Win-win!
Best places to sow: Black-eyed Susans thrive in meadows, flower borders, and roadside plantings. They prefer full sun and well-drained soil.
