About plant names...

Common fleabane is native to North America.

Identification: Plants are up to 3' (1 m) high, with ribbed stems covered with soft white hairs. The hairs grow outward from the stem, rather than lying against it as with some species. A basal rosette of leaves consists of a spatula-shaped leaves up to 4" (10 cm) × 1" (3 cm). The leaves have coarse serrations and may be rounded or pointed at the tip. They may be lance-shaped, but show a wide range of shapes. Leaves higher on the stem usually clasp the stem. Flowers are pale pink, sometimes white, up to ½-¾" (1.3-1.9 cm) around, with 100-300 petals (more than any other fleabane) and a yellow central disk. The petals are so fine that they often look a bit disheveled, like windblown hair. They flower from April to June. The achenes (seeds) have tiny parachutes, like those of dandelions.
