Plants

Swallow-Wort:
At the July 4, 2009 Land Owners Association meeting, it came up that there is a plant called the Swallow Wort growing in this area. It is an Invasive Species plant that can kill trees. Here is an excerp from the following pdf file.

Swallow-wort (Cynanchum rossicum) is an exotic herbaceous twining perennial herb found on calcareous soils in the northeastern U.S. and adjacent Canada. A member of the milkweed family, the species, introduced from Europe more than a century ago, exhibits highly invasive characteristics and is capable of displacing native species over extensive areas. The species is expanding through much of the Great Lakes area.

Hogweed:
Presented July 2009 - They are a large invasive species, up to 12 feet high, which is the size of the one on our eastside common area.

Giant hogweed -- a member of the parsley family -- is striking due to its huge size. In the first year of growth, plants form a bush-like rosette of compound leaves (1 to 5 feet wide) that are deeply incised and pointed. Plants flower in their second year (or later, depending on maturity). Flowering plants are 8 to 15 feet tall, topped with a group of broad, flat-topped umbels of white flowers. Flower stalks can be 2 to 4 inches in diameter, with coarse white hairs and reddish-purple mottling. The bottoms of leaves also have coarse, dense hairs. The plant produces thousands of seeds, then dies after flowering.
