Plant annual wildflowers if you want fast-blooming plants. Grow perennial wildflowers for slow but long-lasting plants. Cultivate biennial wildflowers if you want plants with a 2 year life-cycle.
Annual wildflowers grow and bloom 2-3 months after their seeds are planted, but usually die after 1 season. These flowers bloom for about 2 months before dying with the first frost. Choose from popular options like:  Zinnias, which have bright pink daisy-like blooms Orange cosmos, flowers with vibrant orange petals and yellow centers Prairie asters, small flowers with delicate purple petals Evening primroses, small, cup-shaped blooms that are usually yellow or pink African daisies, which may have orange, pink, purple, red, white, or yellow petals Perennial wildflowers will not bloom until a full season after they are planted, but they can last for decades. Perennials only bloom for about 2 weeks a year, but their roots are winter-hardy and produce growth annually. Plant interesting perennial wildflowers like:  Blanket flowers, which are similar to sunflowers with red and yellow petals Blazing star flowers, which have unique, long purple blooms Forget-me-nots, small flowers with rounded blue petals Wild yarrow flowers, which have clusters of tiny white blooms Coneflowers, yellow or blue blooms also known as echinacea Biennial wildflowers bloom in their second season like perennials, but the flowers die with the first frost the way that annual wildflowers do. Biennial wildflowers seed heavily so there is a good chance of them developing into perennials. Plant beautiful biennial choices like:  Foxgloves, flowers with tall stems and purple, bell-shaped blooms Chicory flowers, delicate blue flowers in the dandelion family Sweet William flowers, which have white blooms with fuschia-colored centers Hollyhocks, flowers that bloom on tall stems in a variety of colors
