Platanthera ciliaris aka Yellow Fringed Orchid

Platanthera ciliaris is a perennial in the orchid family. Gardeners call it the orange fringed orchid or yellow fringed orchid. Its native range spans southern Ontario and the central and eastern United States. It grows in bogs, meadows, sandy woods, and thickets. It also occurs on slopes, roadsides, and some dry uplands. Plants near the northern range edge face several threats. These include collecting, mowing, changes in water flow, and advancing plant cover.

This upright plant reaches 1–3 feet [0.30–0.91 metres] tall. Its garden spread is 1–2 feet [0.30–0.61 metres]. It grows fast and forms small colonies through stolons. These spreading stems produce new plants. The green stems have ridges and lack scent. Smooth leaves grow in an alternate pattern and clasp the stem. Their color ranges from bright green to blue-green. The lower leaves have a lance shape and pointed tips. They reach 1 foot [0.30 metres] long and have unbroken edges.

Orange to yellow flowers form a raceme at each stem tip. Each cluster can hold 35–75 blooms. The flowers open from July through September. They open first at the base, then farther up. A flowering display can last about a month. Each flower has three rounded sepals and two lightly fringed upper petals. The lower lip has a much deeper fringe. A long, thin nectar spur curves down behind the flower. Butterflies and moths visit the flowers and pollinate them. Capsules follow the blooms and hold tiny seeds.

Give this orchid full sun or partial shade. It prefers acid soil that stays wet or boggy. It can cope with drier spells if flowering plants receive enough moisture. The NC State profile lists USDA hardiness zones 8a–10b. Winter pine-straw mulch helps protect roots and makes soil more acid. Seed germination can be hard, so fall root division offers another way to propagate it. The same profile rates routine upkeep as low.

Use this orchid in a native meadow, bog, or pollinator garden. Groups can bring bright flower color to slopes and natural plantings. It also suits containers, and its blooms serve as cut flowers. NC State reports no serious pest or disease problems. Tall flower stems may still need stakes. The supplied sources give no guidance on edible parts or toxicity.
