The wonderful cornflower has a variety of different names, each a sweet description of these lovely annual or perennial flowers. Whether you choose to call them cornflowers, basket flowers or bachelor's buttons, the lovely blossoms remain the same purple, fuzzy gems. Annual cornflowers will self-sow year after year, and perennial cornflowers spread by underground runners--which means you might find yourself with an overabundance of cornflowers growing in a flower garden. Transplant purple cornflowers in the spring to control the spread and minimize crowding.
Prepare a sunny or partially sunny growing area in the spring as the new cornflowers begin to grow. Cultivate the soil down at least 4 inches and add 1 to 2 inches of compost over the top of the soil to enrich it. Work the compost into the soil with the spade, and use the rake to smooth the soil.
Dig holes for the cornflowers with the trowel, spacing holes for annual cornflowers approximately 1 foot apart and holes for perennial cornflowers 2 feet apart.
Remove the cornflowers from their existing location with the trowel. Insert the blade of the trowel 3 to 4 inches away from the plants and push the blade carefully down into the soil. Make a circle around each cornflower with the blade of the trowel and then angle the blade beneath the roots to remove the plant from the soil. Place the cornflower into the basket or bin, removing as many cornflowers as you wish to transplant.
Take the cornflowers to the new planting area immediately and place each cornflower into a prepared hole. Cover the roots with soil and make sure the cornflower is at the same depth as it was previously growing. Pat the soil down firmly around each plant to finish transplanting it.
Water the newly transplanted cornflowers generously immediately after you finish planting them to saturate the soil evenly.
