Bluet Plant – Houstonia caerulea
The Bluet Plant, or the Houstonia caerulea, is a perennial native to North America and one genus of the Rubiacea plant family. Bluet plants are small in size and delicate, with some species growing only an inch tall. Each of the species differ a little but are mostly the same, for example some are single-stemmed while others have bunched multiple stems. Its flowers are different, colorful shades of rose, white, lavender, purple, and blue. Generally, all flower varieties bloom from April into July, and have four petals with yellow centers. To thrive, Bluet Plants need partial shade and moist, acidic soil. Bluet Plants, also called Quaker Ladies, this delicately beautiful plant arrives in April and continues to bloom till July. In the wild, bluets grow in lovely patches in open woods, grassy fields, meadows, green slopes, and lawns. It is a low plant with erect, wire-thin stems that rise from basal leaves about 1/2 inch long. The bluet plant has shallow roots and a rhizome.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 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 see if they want another season of this delightful plant. The seed capsule is about a 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.
