When not flowering, Harperocallis flava, or Harper's beauty, appears very grass like, and can easily be overlooked. The leaves of the rhizomatous, perennial herb are stiff and grassy, 5 to 21 cm tall. However, when this plant flowers, you know why its known as Harper's beauty. This plant's flower is typical of plants in the lily family with 6 petals, 6 stamens, and superior ovary. Each plant bears a single yellow flower, which distinguishes it from all other members of the family in the area, on a stalk much longer than the leaves. The petals are 9 to 15 mm long, spreading when the plant is in flower, erect when if fruit. The petals become green when the plant is in fruit. Harper's beauty flowers from mid-April through May and fruits are mature in July (USFWS 1991)
Distribution & Occurrence
Harper's beauty occurs in wet prairies, seepage slopes, pitcherplant bogs, especially in transitions to shrub zones, and it is sometimes seen in nearby moist roadside ditches. It is found in a small area within the Apalachicola National Forest and vicinity (FNAI 2000). Harperocallis flava occurs in acidic boggy areas in full sun with soil high in sand and peat. It grows more abundantly in places where some degree of soil disturbance has prevented a grass mat from forming (NatureServe 2001).
|Harperocalis flava has been found at three locations, all within the Apalachicola National Forest, approximately 19 miles apart along SP-65 in Franklin and Liberty Counties, Florida. These locations are within 0.3 miles of each other in Franklin County, while a third site is about 19 miles north in Liberty County, although attempts to relocated this site have been unsuccessful. It is estimated that the plant population is several thousand plants (USFWS 1991).|
