Leavenworthia
(named in honour of M. C. Leavenworth, an American botanist, who died in 1862). ORD. Cruciferoe. L. Michauxii thrives in any ordinary garden soil, and succeeds best when treated as a halfhardy annual. Propagated by seeds, sown in the open border, in spring.
L. aurea (golden) is quoted by Dr. Asa Gray as a mere synonym; it is described, however, as having yellow flowers, so would be a desirable variety, from a garden standpoint.
L. Michauxii (Michaux's). fl. rosy-lilac, with a yellow eye, freely produced on erect scapes. June. l. slender, lyrately-pinnatifid, tufted. h. 3in. United States, 1868. (B. M. 5730.)
