Poison Ivy (Toxicodendron radicans)
In bloom June 5 - July 10.
"Leaves three, let it be," goes the old saying.
Leaflets are grouped in three's and usually have a notch on one
side of each leaflet. Both leaf color and shape are variable.
Color can be glossy deep green in the spring and then lighter
green in the summer. In the fall leaves can be bright red. This
plant is very common in the natural area and touching any part
can cause a rash. The plant often occurs as a vine 10's to 100's
of feet long growing on tree trunks, or as a small shrub as small
as a few inches tall growing on the forest floor. Leaves resemble
those of the Box Elder (Acer negundo
) tree. White
clustered berries can remain on the plant all winter.
