Prunella Flowers

Prunella flowers bloom on the Prunella vulgaris plant, which is part of the mint family. The plant is common throughout North America and is easily recognizable. The poem "Designs" by Robert Frost prominently features Prunella vulgaris, also known as heal-all, self heal, woundwort and carpenter's herb. Though some regard it as an intrusive weed, others cultivate it for its aesthetic or medicinal value.
  1. Description

    • Prunella vulgaris is a low-growing weed, usually averaging between 1 and 2 feet tall. It has a square, green, thick stem covered in fuzz. Its dark green leaves end in sharp points and grow opposite each other around the stem. Each prunella stem terminates in a multilayered bud. These buds can produce several tiny flowers, each of which can be blue, lavender, pink or white. The bud and flowers are covered in tiny, fuzzy spines. Prunella flowers bloom for two months in the summer.

    Habitat

    • The prunella plant is native to North America. It is found in every region in the United States, as well as much of Canada. It grows abundantly in fields, gardens, the edges of forests and even roadsides. It does well in moist spots that receive some sun. This plant is persistent and can survive in wet and dry conditions. If this plant is frequently pressed down or walked upon, it will adapt by growing nearly flat against the ground.

    Care

    • You can purchase Prunella vulgaris seeds from your local florist. Plant the seeds in moist soil in a sunny or somewhat shady spot. Place the seeds under 1/16th of an inch of soil. It is best if the soil in which you plant drains well, but prunella will tolerate clay, loamy or volcanic soil, among others. You can plant the seeds when it is no cooler than 55 degrees. You can also plant prunella flowers from cuttings.

    Uses

    • Prunella vulgaris is most well-known for its ability to stop bleeding and disinfect wounds. It also is used to treat throat and mouth irritation. Practitioners of traditional Chinese medicine use this herb to treat disorders of the liver and gallbladder. Some herbal medicine practitioners also advocate its effectiveness for the treatment of ulcers, diarrhea and gynecological complaints. It may also have antibacterial properties and be capable of lowering blood pressure. However, none of these applications have been thoroughly tested and verified. When using the plant for an herbal medicine, you should pick it when the flowers are in full bloom.
