COREOPSIS, TICKSEDED SUNFLOWER; a genus of the synogenesia order, belonging to the polygamia frustanea class of plants. There are 11 species, most of them herbaceous perennials. They are very flowery, and rise from three to eight feet stature; terminated by clusters of compound radiated flowers of a yellow colour. They have all perennial fibrous roots and annual stalks, which rise in the spring, flower from July to October, and decay to the root in November. The flowers are all shaped like sun-flowers, but smaller, and are very ornamental. They are easily propagated by slipping or dividing the roots in autumn, when the stalks decay; planting the slips at once where they are to remain; after which they will require no farther trouble than to be kept free from weeds, and have the decayed stalks cut annually in autumn.
