Lesquerella perforata's common name, Spring Creek bladderpod, derives from the floodplain area in which it grows and the shape of its fruit. This rare plant is now known only from a small area within Tennessee's Central Basin. It's continued survival is threatened by practices that alter its habitat, including residential, commercial, or industrial development, livestock grazing, and encroachment of its habitat by woody and herbaceous perennials. (USFWS 1996)
This species is a lovely winter annual--it germinates in the early fall, spends its winters as a small rosette of leaves, and produces white to lavender flowers in March and April. Soon after these flowers wither, fruit matures and the plants die. Once mature, fruits split open, allowing their enclosed seeds to fall to the ground. Here, the seeds lie dormant until the fall, where this interesting life cycle begins again with seed germination. (USFWS 1996)
Distribution & Occurrence
Typically found growing on flood plains. Some sort of regular disturbance appears to be necessary for the survival of L. perforata. Some types of agricultural practice (i.e. row-crop cultivation) may provide disturbance at the appropriate time and be beneficial to the species. (USFWS 1996)
Often occurs with Echinacea tennesseensis, Juniperus virginiana, Petalostemon gattingeri, Sporobolus vaginiflorus, Dalea foliosa, Arabis perstellata ampla, Thuja occidentalis, and Picea rubens. (USFWS 1996)
|Thirteen extant sites which form a total of 4 populations. Populations can vary in size from year to year, from a few to many thousands of individuals. (USFWS 1996)|
