With dazzling, sky-blue flowers, 'Blue Boy' is wonderful in mass, and because it is drought tolerant, it's practically care free. Flowers can be used dried or fresh cut, while the edible petals make a colorful garnish to salads, crudités platters, or dinner plates. Also known as cornflower, bachelor's button will "naturalize", or self-sow, for another crop of blue flowers next year.

So Easy to Grow

5 out of 5 stars Apr 9, 2020
I love bachelor buttons. They remind me of my grandma, who always had them lining her loooong driveway. When they started looking ratty, she'd just mow them down. They are very drought tolerant and they bloom profusely. They also re-seed easily, so be careful where you put them. They do pull pretty easily, so even if they get away from you they aren't hard to "weed." The bees love them, so I plant them all over my veggie garden and pretty much just let them grow where they want.

Lovely Blue Cornflowers

Ah, these were wonderful, after surviving rabbits that loved to chew the succulent new buds off, they bloomed all summer. I hope they have self seeded. They were absolutely joyful!

The bachelor button seeds did not germinate at all. So I bought seeds from a different company--and they germinated just fine.

These were very easy to get started, I'm waiting on blue blooms. They're vigorous and I succession planted because the first grew so well. Would recommend to someone looking for an easy flowering plant.

Overwhelming Success!

5 out of 5 stars Jul 19, 2021
I planted loads of flower seeds this year and had mixed success due to earwigs eating my young seedlings. The bachelor buttons were sown and all 12 sprouted and were small when I planted them in March. Now in mid July, they are the largest stand of flowers in my bed at nearly 4' tall and the blue bachelor buttons patch is as wide. Tonight we saw the bees hummingbirds and finches all enjoying this delightful blue stand of flowers, and we love them as much our garden pals do.

Very easy to grow. I simply broadcast these seeds in the garden and they took off. Love that pop of blue throughout the garden. Been dropping these seed heads in the garden all season as well for growth in 2022.

Abundant blooms

I winter sowed seed and transplanted into both a large pot and raised garden bed. The latter were sturdier plants and bloomed into mid August beside yellow dill umbels. Pretty.

Were duds this year--only a few germinated, and they only got about 5" tall. This is okay. It's a pandemic year. I'll order them again.
