Description
Pediomelum canescens is a perennial herbaceous species with a bushy growth habit (FSU Herbarium) it grows 1 to 3 feet tall with loose spike of dark-blue flowers and 1 to 3 foliolate leaves. [1]
"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." - Radford et al 1964
"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." - Radford et al 1964
Distribution
Ecology
Habitat
P. canescens occurs in sandy areas of the Coastal Plain [1] 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 (FSU Herbarium). Has been observed growing on drying sand besides roads in open pine-oak woodlands and dry sandy fields (FSU Herbarium). Associated species include Serenoa repens, Quercus incana, Quercus chapmanii, Quercus laevis, Aristida, Andropogon, Onosmodium, bahia grass, and Diospyros (FSU Herbarium).
Phenology
Observed blooming May through October (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [2]
Use by animals
Seeds have been found in bobwhite stomachs (Graham 1941).
