Tall White Lettuce, Prenanthes
altissima
Asteraceae or Sunflower Family
 |
Erect plant, about 2 to 4 feet tall.
Flower heads white to greenish, nodding, bell-shaped, with 5 or
6 ray flowers. Fruits dandelion-like. Leaves highly
variable. Stem leaves usually with shallow irregular lobes
or teeth. The lower leaves usually broad triangular,
toothed, sometimes lobed. Blooms in late summer to fall. Native; prefers woodlands. In Wildwood, fairly common in the woods on the western slope of the Park. Tall rattlesnake root (Prenanthes
trifoliata) has 7 or more ray flowers per head, and leaves
that are generally divided into 3 lobes that are again lobed.
It too likes woodlands and blooms about the same time, but seems
to prefer the eastern side of the Park. |
