Physical Description

Morphology

Description

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].

Habitat 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

Broad-scale Impacts of Plant Response to Fire

More info for the term: frequency

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].

Showy partridgepea most commonly occurs as a pioneer or colonizer of

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].

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].

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].

Relevance to Humans and Ecosystems

Benefits

Value for rehabilitation of disturbed sites

More info for the term: cover

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].

Importance to Livestock and Wildlife

More info for the term: fresh

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].
