General: Sunflower or composite family (Asteraceae; Compositae). Philadelphia fleabane is a native, biennial or short-lived, somewhat weedy, perennial herb. The hemispherical, aster-like flowers (1.5 –2.5cm diameter), which bloom in the spring, have yellow centers of tubular disk flowers (2.5-3cm long), surrounded by from 100-150 narrow, white to pinkish-purple rays (5-10mm long). The flowers grow on branches atop a 30 to 90cm-tall leafless, usually single, stem that grows out of a sparse rosette of basal leaves (4-16cm long). Each branch can bear from a few to several flowers or drooping closed buds. The opened flowers close at night. The basal leaves are ovate (widest near the base) with toothed margins. Another group of smaller, lanceolate leaves surround and clasp the stem near the base. The leaves and stems can be sparsely pubescent to quite hairy. The genus name, Erigeron stems from the Greek eri, "early" and geron "old man," probably because of the
plant’s hairy appearance. The common name “fleabane” is from Old English and it refers to the plant’s odor, which supposedly can repel fleas.
Similar species: Erigeron pulchellus has fewer ray flowers (40-60). E. quercifolius is shorter with violet or blue flowers. E. strigosus is an annual from 30-90cm tall, which lacks the clasping leaves surrounding the stem. Low Erigeron (E. pumilis Nutt.) is from 5-30cm tall and can have white, pink, or bluish rays.
Distribution: For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.
Habitat: Philadelphia fleabane grows in moist to very wet conditions. Plants grow in wet meadows and grassy openings, flood plains, lowland woodlands, thickets, fields, stream banks, low pastures, wet roadsides and seepage areas. The size of the plant varies with habitat.

The plant will grow in a variety of soils. However, it requires soils that are moist and moderately well drained. It grows best in full sun but will tolerate dappled shade.
Seeds: Wildflower seeds should be sown directly into beds or scattered in the garden during early spring. The seeds should germinate in about four weeks.

Relevance to Humans and Ecosystems
Ethnobotanic: The Cherokee and other Native American tribes used Philadelphia fleabane for a variety of medicinal purposes including epilepsy. A poultice was made from the plant to treat headaches. The roots were either made into tea or chewed to treat colds and coughs. The smoke from incense made from the plant was inhaled to treat head colds. A snuff was made and sniffed also for head colds. It was mixed with other herbs to also treat headaches and inflammation of the nose and throat. The tea was used to break fevers. The plant was boiled and mixed with tallow to make a balm that could be spread upon sores on the skin. It was used for as an eye medicine to treat “dimness of sight.” It was used as an astringent, a diuretic, and as an aid for kidneys or the gout. The Cherokee and Houma tribes boiled the roots to make a drink for “menstruation troubles” and to induce miscarriages (to treat “suppressed menstruation”). It was also used to treat hemorrhages and for spitting of blood. The Catawba used a drink from the plant to treat heart trouble.

Erigeron philadelphicus (Philadelphia fleabane) is a plant in the daisy family, Asteraceae. Also known as skevish, skervish, Philadelphia daisy, frost-root, poor robin's plantain, and in the British Isles just as robin's-plantain.
Erigeron philadelphicus is a herbaceous plant with alternate, simple leaves, on hairy stems. The flowers are pink-rayed, yellow centered, borne in spring. The number of closely packed petals ranges from 50 to 100 per flower. The blooms are less than one inch in diameter. The stem is hairy with rough hairs. The middle to lower leaves are heart shaped, and the plant is about 0.5–2.5 ft (15–76 cm) tall. Its active growth period is from spring to summer (April to July). This plant can be found throughout North America along roadsides, in fields, in thickets, and in open woods.
