Description
P. hydropiperoides is a perennial forb/herb of the Polygonaceae family that is native to North America.[1] It is a rhizomatous perennial that often forms mats. The stems are terrete, with a glabrous or strigose texture, and ends that become erect and floriferous. The leaves are 5-10 cm long and 0.5-2 cm wide with a strigose texture. The base is cuneate, the petioles are 1-5 mm long, and the ocrea are 1 cm long. The nutlets are browns, lustrous, and trigonous.[2]
Distribution
Persicaria hydropiperoides is native throughout the continental United States excepting Colorado, Wyoming, and Utah, and has been introduced to Alaska. It is also found in British Columbia, Ontario, and Quebec.[1]
Ecology
Habitat
P. hydropiperoides has a high tolerance for anaerobic conditions and fire, but has a low tolerance for drought. It also requires full sunlight, extremely intolerant to shade.[1]
Habitats for Persicaria hydropiperoides include edges of cypress pond, slash pine flatwoods, and wet swale near bayou.[4] This plant flowers from May through November.[2]
Seed bank and germination
Seeding begins in spring and lasts until the end of summer.[1]
Fire ecology
Populations of Persicaria hydropiperiodes have been known to persist through repeated annual burning.[5]
Herbivory and toxicology
P. hydropiperoides has been observed to host planthoppers from the Delphacidae family such as Delphacodes puella and Pissonotus piceus and plant bugs from the Miridae family such as Lygus lineolaris and Pseudatomoscelis seriatus.[6]
Conservation, cultivation, and restoration
P. hydropiperoides is on the threatened list in Indiana and New York.[1]
