SPECIES: Cassia fasciculata
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Showy partridgepea seeds are a valuable food for northern bobwhite in the Southeast [21,24,34]. Wild legumes, including showy partridgepea, were found to be the most important fall and winter foods of northern bobwhite in the Alabama Piedmont forests of slash pine (Pinus elliotii), loblolly pine (P. taeda), and shortleaf pine (P. echinata) [34]. Seeds of this legume are also eaten by the greater and lesser prairie-chicken, ring-necked pheasant, mallard, brown thrasher, cotton rat, and field mouse [15,29]. The seeds have been found in the food caches of Lousiana pocket gopher [15]. A cathartic substance is present in the leaves and seeds of showy partridgepea. The substance is effective either in fresh plant material or in dry hay [19,39]. Domestic livestock will eat showy partridgepea leaves. However, if large quantities are consumed, the animal may be stressed and die. Deer can eat it without being poisoned [5,39]. PALATABILITY : Showy partridgepea leaves and seeds are presumably palatable to some wildlife species and livestock. NUTRITIONAL VALUE : Showy partridgepea seeds are high in phosphorus content and protein value, and low in crude fiber and lignin. Digestibility of legumes is generally high [31]. COVER VALUE : Showy partridgepea often grows in dense stands, producing litter and plant stalks that furnish cover for upland gamebirds, small mammals, small nongame birds, and waterfowl [15,39]. VALUE FOR REHABILITATION OF DISTURBED SITES : Showy partridgepea is considered an excellent species for planting on disturbed areas for erosion control and improving soil fertility. It establishes rapidly, fixes nitrogen, reseeds, and slowly decreases as other species in the seeding mix begin to dominate the site [8,33]. In one study, showy partridgepea had a nitrogen-fixing potential of 25.9 to 87.0 micro-moles of acetylene daily per plant. It had the fastest growth rate and the greatest nitrogen-fixing potential of the five leguminous species studied. Nitrogen fixation was greatest during the flowering stage [6]. Seeds of showy partridgepea are readily available from commercial seed sources [39]. It has been seeded on soil-lignite overburden, and in the post oak (Quercus stellata) savannah of Texas, where it grew rapidly and had the greatest aerial cover and aboveground biomass of all seeded forbs during the first growing season. It slowly gave way to developing perennials over a period of 3 to 4 years [33]. To prevent weed establishment and control soil erosion along county roadsides in Iowa, showy partridgepea is often included in the seed mix with other forbs and grasses [11]. OTHER USES AND VALUES : Showy partridgepea is commonly grown as an ornamental [39]. In Georgia and Florida it is considered an important honey plant, often occurring where few other honey plants are found. Nectar is not available in the flowers of showy partridgepea but is supplied by the petiolar glands [15,39]. OTHER MANAGEMENT CONSIDERATIONS : Although showy partridgepea foliage is nutritious, it can be poisonous and should be considered potentially dangerous to cattle (see Importance to Livestock and Wildlife) [16].


SPECIES: Cassia fasciculata
GENERAL BOTANICAL CHARACTERISTICS : Showy partridgepea is a native annual legume [15,16,30,39]. It ranges in height from 0.6 inch to 3 feet (0.15-0.91 m) but usually grows to 2 feet (0.61 m) [16,39]. The stems are erect or ascending, branching freely from the base. The leaves are 1.18 to 3.34 inches (3-11 cm) long. Showy partridgepea has a taproot. Secondary roots are well developed, forming a fibrous root system [6]. RAUNKIAER LIFE FORM : Therophyte REGENERATION PROCESSES : Flowers and Fruit: Showy partridgepea flowers are cross-pollinated by bees, flies, and ants [4]. The fruit is a legume containing 9 to 15 seeds [39]. Seeds are ingested and dispersed in droppings of birds and small mammals [15,16,39]. Seed germination: Germination is improved by scarification and stratification [25,39]. Boiling showy partridgepea seeds for 15 to 60 seconds softens the seed coat and increases germination. Nicking the seed with a razor blade will also increase germination [25]. SITE CHARACTERISTICS : Showy partridgepea is common on disturbed areas throughout its range. It often forms extensive colonies along firelines, roadside ditches, and old fields [16,39]. It grows on prairies, bluffs, riverbanks and riverbottoms, as well as upland woods of the Great Plains [39]. Showy partridgepea is common on sandy flatwoods of xerophytic deciduous and coniferous forests in the uplands of the lower Gulf Coastal Plain [26]. Soils: Showy partridgepea is most common on sandy to sandy loam soils [30,39]. It grows best in full sunlight and has low water requirements [30]. The lower pH limit of showy partridgepea is 5.0 [41]. Associate species: Showy partridgepea is often found associated with the following species: purpletop (Tridens flavus), wild-honeysuckle (Gaura filiformis), Canadian horseweed (Conyza canadensis), threeawn (Aristida desmantha), rough bottonweed (Diodia teres), broomsedge (Andropogon virginicus), sassafras (Sassafras albidum), sumac (Rhus spp.), blackberry (Rubus spp.), panicgrass (Panicum spp.), indiangrass (Sorghastrum nutans), sensitive partridgepea (Cassia mictitans), lespedeza (Lespedeza spp.), and ragweed (Amborsia spp.) [3,32]. SUCCESSIONAL STATUS : Facultative Seral Species Showy partridgepea most commonly occurs as a pioneer or colonizer of disturbed areas. It also occupies but is less abundant in mid- to late-seral stages of grassland and forest succession [6,11,38]. Showy partridgepea was most abundant in the initial community following harvest of all but a few scattered oaks (Quercus spp.) in a east Texas upland forest. It was found to be considerably less abundant in adjacent uncut wooded areas [38]. SEASONAL DEVELOPMENT : Showy partridgepea generally flowers from June through October [6,22,30,39]. In years of normal rainfall, the bright yellow flowers appear continously through most of the growing season [16].


SPECIES: Cassia fasciculata
FIRE ECOLOGY OR ADAPTATIONS : Showy partridgepea is favored by frequent fire. Both on-site, fire-scarified seeds and off-site seeds are an important source for colonizing burned areas [1,35,36,37]. POSTFIRE REGENERATION STRATEGY : Ground residual colonizer (on-site, initial community) Secondary colonizer - off-site seed


SPECIES: Cassia fasciculata
IMMEDIATE FIRE EFFECT ON PLANT : Fire will kill showy partridgepea [35,37]. High-severity fires may consume seeds stored in the seed bank. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Showy partridgepea generally increases in abundance after fire and will decrease in the absence of fire or other disturbance [1]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : Showy partridgepea greatly increased in frequency following two spring fires in consecutive years at a southern Illinois barren. However, it showed a rapid decline in frequency following fire cessation. Sampling took place during the summer after each burn. Following the spring fire in 1970 showy partridgepea quadrat frequency was 64; however, by postfire year 15, quadrat frequency had declined to 2 [1]. FIRE MANAGEMENT CONSIDERATIONS : Prescribed fire can greatly increase the quantity and availability of showy partridgepea seed to northern bobwite and other wildlife species [25]. If managing areas for the maintainence of showy partridgepea, the season of burning is important. If burned as early as January, the fire-scarified seed may germinate prematurally, and the seedlings may be killed by March frosts [35,36,37]. Burns should be conducted after the danger of late frosts has passed and before growth has started [35]. Nitrogen is a main nutrient lost during fire. Showy partridgepea can be planted on burned sites to restore nitrogen to the soil [42].
