May is the sweet spot in Minnesota for direct seeding flowers. The soil is finally warming up, the danger of frost is mostly behind us… fingers crossed… and these flowers actually prefer to be planted right into the ground.

Even better? These are all beginner-friendly flowers that keep producing the more you cut them.

One important tip before you start throwing seed packets into your cart at the big box stores:
Buy the varieties that grow TALL.

Most flowers sold at garden centers are bred to stay short and compact for landscaping pots and flower beds. Pretty? Sure. Great for bouquets? Not really. You want the varieties meant for cutting gardens so you can actually bring armloads inside all summer long.

What Does “Direct Sowing” Mean?

Direct sowing simply means throwing seeds right into the garden where you want them to grow instead of starting them indoors first.

It’s about as low maintenance as gardening gets. Scratch up the soil, sprinkle the seeds, lightly cover them with dirt, and keep them watered while they germinate. Easy peasy.

Most seed packets will tell you how deep to plant them, but a good rule is not to plant them too deep. Tiny seeds especially don’t want to be buried.

Once the weather warms up, these flowers take off fast.

1. Zinnias

If I could only grow one flower for summer bouquets, it might be zinnias. They love heat, they grow fast, and the more you cut them, the more blooms they push out.

Benary Giant zinnias are one of our favorites because they grow tall with huge blooms and strong stems. The butterflies love them!

Plant them in full sun, keep them watered while they’re getting established, and once they take off, they’ll bloom until frost.

2. Marigolds

Marigolds don’t get enough credit in the cut flower world. The tall varieties are loaded with blooms and add the prettiest golden, burnt orange, and creamy tones to bouquets.

They’re easy.
Direct sow them, water them, and they pretty much handle the rest.

Plus they bloom nonstop all summer long. You can buy varieties that do not smell like marigolds.

3. Sunflowers

Nothing says summer like sunflowers taller than your kids.

These are one of the easiest flowers to grow from seed, and they germinate FAST once the soil warms up. If you have little kids helping in the garden, this is the flower that keeps them interested because they pop up quickly.

For bouquets, look for branching sunflower varieties instead of the single-stem giant types. Branching sunflowers keep producing multiple blooms instead of just one giant flower.

4. Celosia

Celosia is the weird, funky flower that ends up stealing the show in bouquets. Some look feathery, some look flame-like, and some honestly resemble brain coral.

These thrive once the weather gets hot and they love Minnesota summers. The colors are vibrant and they last forever in bouquets. Plus they dry well.

Again — buy the tall varieties meant for cutting gardens.

5. Cosmos

Cosmos are for the people who want their flower garden to look effortless and magical.

They sway in the wind, attract pollinators, and just keep blooming the more you cut them. They’re one of the easiest flowers for beginners because they don’t need much fussing.

In fact, cosmos almost do better when you leave them alone a little.

They add that soft, airy look to bouquets that makes everything feel straight out of a Pinterest photo… except you grew it yourself.
