18 Self-Seeding Flowers That Produce New Blooms Every Year—With Less Work for You

All of these flowers drop seeds in the garden, which germinate and give way to blooms the following year.

Planting flowers that self-seed is a wonderful way to ensure you'll have blooms each growing season with minimal work on your end. Before they die, these plants drop seeds in your garden that will germinate on their own the following year, providing unexpected blooms and color to your landscape. 

Self-sowing plants are also a big draw for pollinators. These plants are some of the first to flower, meaning they're an early pollen and nectar source for birds, butterflies, and other wildlife. Plus, self-sowing plants are also known for being low-maintenance. Once established, they often require little care beyond what the natural climate has to offer.

Ahead, we're sharing expert-recommended self-seeding flowers you should grow in your garden.
