Scutellaria

(from scutella, a dish or platter; alluding to the form of the fruiting calyx). Helmet Flower; Skull-cap. SYN. Cassida. ORD. Labiatae. A genus comprising about ninety species of stove, greenhouse, or hardy, annual or perennial herbs or sub-shrubs, decumbent or diffuse, rarely erect and tall, very rarely shrubs; they are scattered over temperate regions and the tropical mountains. Flowers blue, violet, yellow, or white, solitary or in pairs, axillary or in terminal spikes or racemes; calyx campanulate, two-lipped, the tube dilated opposite the posterior lip into a broad, flattened, hollow pouch, both lip and pouch deciduous in fruit, the anterior lip closed after flowering, persistent; corolla tube long, naked inside; limb bilabiate, the upper lip entire or notched, the lower dilated, its lateral lobes free and spreading, usually connate with the upper lip, rarely with the lower; stamens four. Nutlets sub-globose or depressed. Leaves often toothed, sometimes pinnatifid or entire; floral ones conformed or changed into bracts. S. galericulata and S. minor are the British representatives of the genus. The species described below are, for the most part, very handsome when in flower, and hence are well suited for ornamenting the front of flower borders. Any common garden soil is usually suitable. The herbaceous species may be increased by seeds, or by divisions; and the shrubby kinds may be readily multiplied by cuttings. S. Mociniana is one of the most beautiful of stove, flowering plants, and may be easily grown by anyone with a cool stove or warm greenhouse temperature. The bunches of flowers are freely produced--one on the point of almost every shoot--and are very bright and effective. Cuttings of half-ripened shoots root readily in spring, or at almost any season, in a warm propagating-frame. Young plants should have their points pinched out once or twice when growing, to encourage a bushy habit, and so insure a much larger production of flowers. Nice little specimens may be grown in 5in. pots. They succeed best in loam and leaf soil or decayed manure, with some sand intermixed. Except where otherwise indicated, the species here given are hardy, herbaceous perennials.
