roots are almost certain to rot; but it will thrive well
and flower abundantly if planted in a light sandy soil
in a dry situation, or if it be cultivated in a pot. A
mixture of turfy loam, peat, and sand, will suit it very
well. It is also a desirable plant for ornamenting rock-
work ; and may be increased by dividing the roots, or
by seeds.
Our drawing was taken from a fine strong plant,
in the Apothecaries’ Garden, Chelsea, last summer.
