BARBAREA (anciently called Herb of St. Barbara). Winter Cress; American Cress. ORD. Cruciferoe. Hardy glabrous perennial herbs. Flowers yellow; racemes erect, terminal. Stems erect. They are of easy culture, but scarcely worth growing in the pleasure garden. Propagated by cuttings, suckers, divisions, or seeds. BARBAREA praecox (early). l., lower ones lyrate; terminal lobe ovate; upper ones pinnate-parted; lobes linear-oblong, quite entire. h. 1ft. to 1 1/2ft. Commonly known as American, or Black American Cress. Here and there on roadsides, and in dry gravelly places in Great Britain. An escape from cultivation. (Sy. En. B. 124.) BARBAREA vulgaris (common). l. lower ones lyrate; terminal lobe roundish; upper ones obovate, toothed, or pinnatifid. h. 1 1/4ft. The double flowering form of this native species is the only one of this genus worth growing for beauty; it is generally known as Double Yellow Rocket. The variegated form is also rather pretty, and comes true from seed. (Sy. En. B. 120.)
