Description
A description of Polygonum nesomii is provided in The Flora of North America.
Distribution
P. nesomii can be found in sandy habitat throughout Florida.[1]
Ecology
Habitat
In the Coastal Plain in Florida, P. robusta can occur in sandy old fields, Florida rosemary scrubs, sand dunes, and xeric oak/saw palmetto scrubs.[2] Associated species include saw palmetto and scrub oaks.
Phenology
The flowers range from light pink to deep pink with the colors changing as the flowers mature and age, eventually turning rusty orange.[3] Blooms throughout summer and fall.[4]
Seed bank and germination
Lindon and Menges (2008) found that germination rates under smoke was less than without smoke.
Germination rates are negatively affected by the allelopathic chemicals leached from the Florida rosemary.[5]
Fire ecology
P. nesomii is an obligate seeder. Weekley and Menges (2003) found that two years post fire, there were individuals established in new areas.
Pollination
The following Hymenoptera families and species were observed visiting flowers of Polygonella robusta at Archbold Biological Station:[6]
