Roses and Iris'

Multiflora rose, despite its wonderful scent, is an invasive species, found in both wetlands and uplands, excludes native plants from growing by crowding them out of their natural habitat. The thickets these roses bushes create can become so large and dense they have been planted roadside as a natural crash barrier.
Its cousin, the swamp rose (Rosa palustris) is found in moist soils, but can also thrive in drier soils, is also very fragrant, found with larger, pink flowers. It is an anolomy among roses, which almost as a rule, do not tolerate "wet feet".
Moving further down the trail, I was not able to find any blue flag, (Iris Versicolor), the defacto natural wetland iris found in the Northeast, but I did discover a stand of yellow iris' (Iris pseudacorus) on the north eastern shore of the lake. The yellow iris is the only yellow iris in the US and will grow in upto 1 foot of water. It is also considered invasive for the same reasons as the multiflora rose, it excludes all other plants from the area by growing large stands of plants.
