Description
Pediomelum canescens is a perennial herbaceous species with a bushy growth habit,[2] it grows 1 to 3 feet tall with loose spike of dark-blue flowers and 1 to 3 foliolate leaves.[3]
"Perennial herbs, subshrubs or shrubs, more or less postulate-glandular. Leaves odd-pinnate or palmate, (1) 3-5 (7) foliolate, stipules usually persistent. Racemes or spikes pedunculate, axillary and sometimes also terminal; flowers papilionaceous. Calyx persistent, the lowermost lobe the longest or rarely all nearly equal; petals 5, blue-purple or rarely white; stamens 10, rarely 9, diadelphous or weakly monadelphous; ovary sessile or stipitate, usually 1-ovuled. Legume usually not much longer than the calyx, often conspicuously wrinkled, indehiscent or irregularly dehiscent, 1-seeded."[4]
"Coarsely canescent, perennial herb, 3-10 dm tall, from a subglobose or fusiform root 2.-4 cm thick. Leaves palmately 3-foliolate or the uppermost sometimes 1-foliolate; leaflets elliptic to obovate, mostly 1.5-6 cm long, 1-3 cm wide, eglandular to abundantly but inconspicuously glandular-punctate on both surfaces. Racemes loosely few-flowered, 2-6 cm long; peduncles 2-7 cm long, pedicels 3-6 mm long, each subtended by an ovate bract 4-6 mm long. Calyx appressed to spreading villous; petals blue or violet, 8-15 mm long. Legume ovoid, ca. 1 cm long, dehiscent."[4]
Distribution
This plant is a Southeastern Coastal Plain endemic. It ranges from southeastern Virginia, south to peninsular Florida, Panhandle Florida, and southern Alabama.[1]
Ecology
Habitat
P. canescens occurs in sandy areas of the Coastal Plain[3] such as longleaf pine-turkey oak sand ridge, secondary longleaf pine-turkey oak sand-hill ridge, longleaf pine-wiregrass sandridge, pine flatwoods, and open sandridges.[2] Has been observed growing on drying sand besides roads in open pine-oak woodlands and dry sandy fields.[2] Associated species include Serenoa repens, Quercus incana, Quercus chapmanii, Quercus laevis, Aristida, Andropogon, Onosmodium, bahia grass, and Diospyros.[2]
Phenology
P. canescens flowers from May through July and fruits from July through October.[1]
Seed dispersal
This species is thought to be dispersed by gravity.[5]
Fire ecology
Populations of Pediomelum canescens have been known to persist through repeated annual burning.[6]
Herbivory and toxicology
P. canescens seeds have been found in the stomachs of bobwhite qual.[3]
