Tall Blue, Centaurea Seeds

The Tall Blue Cornflower produces a dazzling display of drought resistant, beautiful dark blue flowers that are attractive when cut or dried. This variety is an annual that will "naturalize" yearly when the seed drops. It readily comes back the next year to produce another crop of blue flowers. In warm climates, plant the Tall Blue in summer to early fall for winter bloom.

    Learning Download: How to Grow Cornflower

The Cornflower is also known as the bachelor button, and it can be harvested in the summer or fall depending on when it is planted. Cornflower can reach 3 feet in height and attract birds and butterflies. Blooms can reach up to 1 inch wide.

Before Planting: Cornflower is not picky when it comes to soil conditions, but it does prefer a sunny location to grow. Prior to planting, loosen the soil in the garden and amend it with 4 inches of compost.

Planting: Plant the seeds one week before the last frost of the season. Plant them 1/4 inch deep and 1 inch apart.

Watering: Water the flowers 1 inch per week.

Fertilizer: Feed the Cornflower with an all-purpose fertilizer once a month.

Days to Maturity: Cornflowers begin flowering in early June and will continue to flower through August. Sometimes, they can even begin flowering in March if planted in a warmer climate.

Harvesting: Cornflowers make a great cut flower to bring inside and also work for dried flower arrangements since the flowers retain their color even after being dried.

Tips: Cornflowers are hardy, but they can be susceptible to mold and mildew if overwatered and not given enough space for good air circulation.

Our Seed Promise

"Agriculture and seeds" provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants.

The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats. We feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to further assess the potential risks of genetically engineered seeds. Further, we wish to support agricultural progress that leads to healthier soils, to genetically diverse agricultural ecosystems, and ultimately to healthy people and communities.
