Plant These 8 Easy Flowers from Seed for Beautiful Summer Blooms

If you’ve been thinking that a beautiful flower garden means lots of work and upkeep, you need to take a look at these flowers. These heirloom varieties are the easiest flowers to grow from seed.

We recommend them to beginner gardeners because we know they’ll be successful and enjoy a colorful display of blossoms all summer.

There’s a reason that these easy flowers to grow from seed always appear in our flower garden.

Not only are these varieties fast and easy to grow from seed, but some, like zinnias and cosmos, let you keep cutting them, and they’ll keep growing more flowers.

All these flowers will attract pollinators to your garden, so feel free to add them around your vegetables, too!

Zinnias top our list of the easiest flowers to grow. They germinate quickly and can be started indoors or sown directly outside.

Zinnias seem determined to bloom no matter what, and the more you cut them, the more they grow.

Zinnias come in a variety of bright colors and even Polar Bear white. The blooms on the California Giants can be 5 inches wide.

Growing a mix of bright-colored Zinnias is a visual joy and will attract local pollinators. With different varieties and colors to choose from, you can have a field of mixed colors or planned sections of all the same color.

Zinnias are one of the most rewarding flowers to grow. Enjoy a whole garden of zinnias all summer long. 

Yellow sunflowers are always a welcoming sight. But sunflowers don’t just come in yellow. You can plant heirloom sunflowers in a range of colors, from lemon yellow to dark chocolate cherry. In addition, sunflowers come in various shapes, from the fluffy Dwarf Sungold to the seed-filled Mammoth Sunflower. There’s also a variety of sizes from 5 to 12 feet tall.

Bees, butterflies, and birds all love sunflowers! Plant a few extras to share the seeds with the birds.

Sunflowers can be used in all kinds of landscape designs. They are also beautiful in cut flower arrangements.

Cosmos are annual flowers that come in shades of pink and white. They happily grow in full sun and bloom all summer and fall.

Most cosmos have a daisy-like shape, but the Sea Shell variety has a curved petal. The fern-like foliage grows from 3 to 5 feet high. Bees and butterflies will be happy to flit from flower to flower as they gently blow in the breeze.

These flowers work in a tall border design as well as a wildflower garden. Cut them off for bouquets, and they will regrow. Cosmos will also reseed for another year of blooms.

Calendula is both a beautiful annual flower and a medicinal herb. 

Heirloom calendula varieties mature quickly and produce continuous blooms, making them popular in flower gardens. 

Calendula blooms range in color from yellow to orange and have been used for centuries to dye fabrics, foods, and cosmetics. 

Healthy calendula plants have more blooms than foliage. You can keep picking the flowers, and they’ll keep growing more. Calendula will even bloom and grow through the winter in temperate regions.

Our nasturtium collection will produce a nice mix of foliage with elegant red, yellow, orange, and gold blossoms. Not only are nasturtiums easy to grow, they are also edible. Both the leaves and flowers have a peppery zest that can be added raw to salads and other dishes.

Nasturtium look beautiful in manicured landscape beds and are also right at home in a laid-back cottage garden. They even work hard as companion plants and deter pests such as the cabbage looper.

Enjoy nasturtium outside in the garden and indoors as a cut flower.

If you’re looking for a carpet of flowers, look at Sweet Alyssum. The sweetly fragrant flowers make a delicate edging along borders. Perfect for smelling as you walk by.

Sweet Alyssum seeds germinate in only 5 to 14 days. They grow 4 to 6 inches tall with either white or purple flowers.

Start Sweet alyssum seeds indoors for early blooms. Sweet alyssum can grow in part-shade, so they can be planted to fill in spaces between other flowers.

Filling your landscape with blooming flowers is not only beautiful to look at, but it contributes to a healthier environment. Flowers provide food and enrich the natural habitat for butterflies, bees, and other beneficial pollinators.

When you grow heirloom flowers from seed, you won’t have to wait for transplants to show up in your garden store. Plus, you’ll have the added benefit of being able to save your favorite seeds for more flowers next year. 

It’s easy to grow flowers from seed; these beautiful varieties are just the beginning. 

Plant some heirloom flowers this year and do something good for your soul and our natural environment.
