The leaves of the bluet are oblong and come in tufts. The branchless stems bear tiny leaves and four-petaled flowers that are about a 1/2 inch wide. They are pale blue, usually, with bright yellow centers. The flowers either have long stamens, which are the male parts of the plant and a short style, which is the female part of the plant or short stamens and a long style. The plant grows to about 6 to 8 inches high.
The bluet grows best in part shade and in moist soil that's on the acidic side. They need average watering. It grows easily in lawns, but the gardeners should take care not to mow the lawn before the bluets have gone to seed if they want another season of this delightful plant. The seed capsule is about an 1/8 inch across and has two lobes. If looked at under a magnifying glass, the gardener will see a pebbly surface.
The bluet attracts bees, birds and butterflies to pollinate it. Few sights are as lovely as a bluet being visited by a tiny common blue butterfly. Bluets are especially pretty tucked among the crags in a rock garden, where their soft blue plays against the hard gray or brown of the rocks.
The plants can be started from seed, and they should be planted at a shallow depth. Bluets sprout the first year but bloom in the second year and grow best in hardiness zones 3a to 8b.
