Platanthera grandiflora (Bigelow) Lindl.
Greater Purple Fringed Orchid
Orchidaceae (Orchid Family)
Synonym(s): Blephariglotis grandiflora, Habenaria fimbriata, Habenaria grandiflora, Habenaria psycodes var. grandiflora
USDA Symbol: PLGR2
Deeply fringed, fragrant, lavender flowers in many-flowered, elongated clusters on a leafy stem.
A close-up of the individual flowers reveals the striking beauty of the fringed orchids. The method of pollination by moths is interesting. The pollen masses (pollinia) bear a sticky disk that protrudes below the anther. As the moth extends its tongue into the spur of the lip petal and then out again, it pulls the pollen mass from the anther and carries it to another flower where cross-pollination occurs. Small Purple Fringed Orchid (P. psycodes), occurring from Manitoba east to Newfoundland, south to Georgia, and northwest to Tennessee, Missouri, and Minnesota, has smaller flowers. Purple Fringeless Orchid (P. peramoena) has an unfringed lip petal; it grows from Pennsylvania and New Jersey south to Georgia, west to Arkansas, and north to Missouri and Illinois.
