Norway Maple (Acer platanoides) Japanese Barberry (Berberis ...

Burdock (Arctium minus)
Status: Exotic.
Native to: Europe.
Effects: Indirectly affects the development of crops by
hosting powdery mildew and root rot. Reduces value of
sheep’s wool when its seed heads get entangled in it.

Distinctive features: In its first year of growth this
plant grows as a rosette near the ground. Then, in the
second year, it sends up a stout, grooved, rough stem
with multiple branches that grow 2-6 feet tall. The
large, heart-shaped leaves are dark green and smooth
above and whitish green underneath. They attach to the
stem alternately rather than opposite one another. This
plant produces numerous pink, purple or white flowers
clustered together in flowering heads that are about ¾
inch across. Each head is enclosed in a prickly burr with
numerous hooked spines on its tips. This plant flowers
between July and October.
Queen Anne’s Lace (Daucus carota)
Status: Exotic.
Native to: Europe.
Effects: Because it spreads rapidly by seed and springs
back after mowing, this biennial plant is considered a
serious pest in some states.

carota-0192.jpg
Distinctive features: A close relative to the domestic
carrot, this plant’s leaves look very similar. The first
year, the leaves form a rosette, then the second year a
coarsely hairy flowering stem is produced that can grow
to more than 3 ft. in height. Leaves sprouting from the
flowering stems are alternate. A flat-topped cluster of
small, white flowers forms at the top of the stem. The
presence of a single reddish purple flower in the middle
of this cluster is distinctive of the species, but is not
always present. A similar-looking member of this plant
family, Poison Hemlock, has grooved, purple-spotted
stems and is hairless.
