VALUE AND USE
SPECIES: Sarracenia purpurea | Pitcher-Plant
WOOD PRODUCTS VALUE :
NO-ENTRY
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Pitcher-plants, although carnivorous, are also beneficial to several
insect species. Ants, wasps, bees, butterflies, and moths are attracted
to pitcher-plant by its nectar. Beetles and spiders visit the plants to
prey on other insects. Spiders may spin a web inside the pitcher to
catch insects which fall inside [16]. Some flies live in the pitchers,
feeding on decomposing insects [9]. The larvae of a small, nonbiting
mosquito live only in the liquid held by pitcher-plant. Unlike most
insects, these larvae are neither killed nor digested in the pitcher
fluid [9,26].
Pitcher-plant obtains prey species that are quite different from that of
other Sarracenia species. A large number of grasshoppers, crickets, and
snails are captured. Microhabitat segregation exists among
Sarracenica species in the same bog and may influence the types of prey
obtained [9].

VALUE FOR REHABILITATION OF DISTURBED SITES :
Runoff from road-salt storage piles into an adjacent bog killed several
native bog species, which allowed the invasion of cattails (Typha
latifolia) and weedy annuals. Several bog species, including
pitcher-plant, were successfully transplanted to damaged areas using
"living mats" from unimpacted areas of the bog. Component species of
the mats included Sphagnum mosses, small cranberry (Vaccinium
oxycoccos), pitcher-plant, narrow-leaf sundew (Drosera intermedia), and
leatherleaf (Chamaedaphne calyculata augustifolia) [27].
OTHER USES AND VALUES :
The unique beauty and unusual mode of life of pitcher-plants make them
desirable as houseplants [8].
MANAGEMENT CONSIDERATIONS :
The larvae of several moth species feed on or burrow in pitcher-plant,
sometimes infesting large areas and severely damaging the population
[26].
Collection of wild pitcher-plants for sale has resulted in localized
extinction in some areas. A number of dealers currently specialize in
cultivating carnivorous plants, but collecting is still a problem, since
it is less costly [8].
