May is an excellent time to start planting flower seeds in your garden. The warmer weather and longer days create ideal conditions for young plants to thrive. Choosing the right varieties can lead to a vibrant, colorful garden throughout the summer and into the fall.
Why Start Flower Seeds in May?
Starting flower seeds in May allows seedlings to develop strong roots before the peak growing season. It also gives you a head start on blooming, ensuring a lush display of flowers during the summer months. Additionally, many annuals and perennials benefit from being started indoors or in a protected environment before transplanting outdoors.
Best Flower Varieties to Start in May
Sunflowers
Sunflowers are easy to grow and bring cheerful brightness to any garden. Start them indoors in May for an earlier bloom or sow seeds directly into the soil after the danger of frost has passed. Varieties like ‘Autumn Beauty’ and ‘Mammoth’ are popular choices.
Marigolds
Marigolds are hardy annuals that thrive in full sun. They are excellent for borders and containers. Starting marigolds in May ensures vibrant, pest-repelling flowers all summer long. Varieties such as ‘Crackerjack’ and ‘French Marigold’ are widely loved.
Zinnias
Zinnias are known for their bright, bold colors and are perfect for attracting butterflies. Sow zinnia seeds indoors in May or plant directly outside after the last frost. Popular types include ‘California Mix’ and ‘Lilliput.’
Cosmos
Cosmos are tall, airy flowers that bloom profusely in summer. They prefer full sun and well-drained soil. Starting cosmos seeds indoors in May gives them a head start for a long flowering season.
