Cornflower (Centaurea Cyanus Dwarf Tom Pouce Blue) - Also known as Bachelor's Button, these well-known drought tolerant annuals make great cut flowers for fresh or dried arrangements. Grow them easily from seeds, and display these sky-blue flowers in the flower border or garden. The dwarf variety makes the perfect size for containers too. Remove spent flowers to extend the bloom season and to increase the flower size.

Centaurea Cyanus plants prefer full sun in mild climates and partial shade in the hottest regions. They tolerate a wide variety of soils as long as it drains well. Cornflowers perform the best in mild climates with moderate water, but they can withstand drought. Bachelor's Button flowers are very attractive to both bees and butterflies, but deer leave the plants alone.

Directly sow seeds outdoors in early spring as soon as soil can be worked. Prepare seedbed by loosening soil and weeding. Sow the flower seeds in rows, 6 seeds per foot. Thin seedlings to 6 - 12 inches apart. In mild winter climates, seed can be sown in the fall for very early blooms the following spring. Cornflower can re-seed to bring you beautiful new plants.

In a wildflower garden, plant cornflower to attract bees and butterflies. Alternatively, in a cutting garden, pair blue cornflower with annuals such as orange cosmos or yellow marigolds. Grow cornflower alongside robust perennials like rudbeckia or coneflower to provide natural support for its stems.

Q

Do I need to deadhead my cornflowers?

A

You can increase our bloom season if you deadhead your flowers. Deadheading however is not necessary.

Q

How can I encourage more blooms?

A

Cornflowers thrive in bright and sunny environments, so it's crucial to plant them in a sunny location. If your cornflowers aren't blooming because of inadequate light, your best option is to plan ahead for the following year and sow them in a sunnier area.

Q

How Long Does Cornflower Bloom?

A

Cornflowers usually flower for approximately 10 weeks, from May to mid-July. Extending the bloom time can be achieved by seeding the flower every two weeks on a staggered schedule.

Q

Can I grow my cornflower in containers?

A

Yes, when cultivating cornflowers in pots or containers, it's important to maintain slightly dry soil to replicate pasture environments. Opt for porous clay or terracotta pots for best results. Select well-draining soil with perlite, or opt for a soilless mix composed of organic materials (similar to cactus potting soil). Regularly remove faded blooms from your potted cornflowers to keep them looking neat. Expect a brief flowering period when grown in this manner. Shorter varieties work best in containers.
