Lysimachia quadrifolia L. Whorled loosestrife, yellow whorled loosestrife, whorled yellow loosestrife
Whorled loosestrife is a North American native. The genus Lysimachia recognizes a Greek general and king of ancient Thrace (Sicily), Lysimachus. He is said to have calmed a maddened bull using a plant from this genus. The species quadrifolia simply means “four leaves,” since each whorl of leaves in this plant most often consists of four leaves. Plants: 12-36" (30-91 cm) in height, with a smooth, erect stem that is rarely branched. Leaves: In whorls around the stem, like spokes in a wheel. Each whorl contains 3-7 leaves, usually 4. Leaves are roughly oval, narrow, with sharp tips and hairy underneath. Flowers: Starlike, with five pointed yellow petals, and a red spot in the center. The flowers are also in whorls, on long petioles arising from the same points where the leaves emerge from the stem. Each flower is ⅜-½" (9.5-12 mm) in diameter. They bloom in June and July.
