About plant names...
Pineweed (also called orange grass) is a native of North America.
Plants: I first noticed pineweed because of its tiny red fruits,
growing on thin plants that seem to consist of stems without leaves. I wondered if this was even a "regular"
flowering plant—it looked like a ground pine or something similar. Its stems are wiry and green. It reaches
3-18″ (7.6-45 cm) in height, usually about 6″ (15 cm).
Leaves: Tiny and narrow, about ¼″ (6.3 mm) long.
Flowers: Tiny yellow flowers up to ¼″ (6.3 mm) across appear in the spring.
Fruits: The fruits in the fall tip the multiply
branched stems with pointed, dark red tips
