This is Centaurea cyanus Polka Dot Mix, also known as Bachelors Button, and Cornflower. This Annual plant is very popular with the hummingbirds, regular birds, bees, and butterflies. Growing to about 2 feet high, this plant must live in the full sun. The blossoms are lavender, blue, pink, burgundy, and white. This plant is a super nectar factory in the sense that the leaves produce nectar even when the plant is not in blossom. The extra sweet nectar from this plant also draws in flower flies, lacewings, ladybugs, and many other beneficial insects. The beautiful blooms will also make for a nice cut flower. These flowers were used in constructing the funeral wreath for King Tut. This is a nectar plant for the Painted Lady butterfly.
