The garden fleabanes are practically all perennials. A few annuals are harmless and pretty weeds. Some species have roots that are biennial, but they increase by offsets, and make larger clumps from year to year. They are of easy culture. They do best when somewhat shaded from the midday sun. They are easily propagated by seeds or division, and doubtless by cuttings, if there were sufficient demand. Small, divided plants set out in early spring produce good- sized flowering plants the first year. A good show of bloom may be had from seeds sown outdoors as early as possible in spring. Some fine masses of these plants in the hardy border or wild garden are much more desirable than an isolated specimen or two of each kind. The most popular species is E. speciosus. At present it is the best kind that has the rich soft colors, from rose to violet and purple. E. aurantiacus has dazzling orange flowers, and is unique in the genus.

Erigeron (Greek, old man in spring; some of the early kinds are somewhat hoary; syn. Stenactis Cass.)). Compositae. Flea-Bane. Hardy border plants, suggesting native asters, but blooming much earlier, growing in tufts like the English daisy, though usually from 9 inches to 2 feet high.

Stem-lvs. entire or toothed: fls. solitary, or in corymbs or panicles; rays in 2 or more series, mostly rose, violet or purple, rarely cream-colored or white, and one kind has splendid orange fls.; involucre bell-shaped or hemispheric, the bracts narrow, nearly equal, in 1 or 2 series, differing from Aster in which the bracts are in many series.—About 150 species scattered over the world, particularly in temperate and mountainous regions.

The garden fleabanes are practically all perennials. A few annuals are harmless and pretty weeds. Some species have roots that are biennial, but they increase by offsets, and make larger clumps from year to year. They are of easy culture. They do best when somewhat shaded from the midday sun. They are easily propagated by seeds or division, and doubtless by cuttings, if there were sufficient demand. Small, divided plants set out in early spring produce good- sized flowering plants the first year. A good show of bloom may be had from seeds sown outdoors as early as possible in spring. Some fine masses of these plants in the hardy border or wild garden are much more desirable than an isolated specimen or two of each kind. The most popular species is E. speciosus. At present it is the best kind that has the rich soft colors, from rose to violet and purple. E. aurantiacus has dazzling orange flowers, and is unique in the genus. CH
