This species, a native of the Alps, of Switzerland, and Austria, is frequently kept in gardens for the sake of variety; like the rest of the genus, it flowers early in the spring, in March and April; is a very hardy perennial, increases most readily in a moist shady situation, is usually kept in pots for the convenience of sheltering it in very severe seasons; but it will grow readily enough in the open border. All plants that flower early, though ever so hardy, require some kind of shelter, previous to, and during their flowering.
Is propagated by parting its roots in autumn.
