Cornflower (Centaurea Cyanus Fantastic Mix) - For a beginning gardener, cornflower seed is a great flower seed to start with. The flower seeds are larger, so they are easy to handle, and they germinate easily and produce blue and white blooms in about 10 weeks after being planted. When your neighbors seed this mix of flower they will definitely be asking what you planted. Of course, you will know it's our Fantastic Cornflower seed mix. With long-lasting blue and white spring blooms, it is the perfection addition to any flower garden and great for xeriscaping.
The mature 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 do tolerate drought. Centaurea Cyanus plants are very attractive to both bees and butterflies, but deer leave them alone. Bachelor's Button flowers also make an excellent cut flower for both fresh and dried arrangements.
Directly sow Bachelor's Button 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. You will want to thing seedlings to 6 - 8 inches apart for best results. In mild winter climates, Cornflower seeds can be sown in the fall for very early blooms the following spring. Like many flowers in your garden, this wildflower can self-sow.
Common Questions
Where should I plant cornflower?
Enhance your ornamental vegetable garden by incorporating the versatile cornflower. Its nectar content attracts pollinators, benefiting the yield of tomatoes, squash, and other dependent 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.
Do I need to deadhead my cornflowers?
You can increase our bloom season if you deadhead your flowers. Deadheading however is not necessary.
How can I encourage more blooms?
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.
How Long Does Cornflower Bloom?
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.
Can I grow my cornflower in containers?
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.
