Beautiful and hardy as this plant is, and long as it has been introduced to this country, we do not find it generally in gardens; we attribute this to its having, in a greater degree than many other plants, a partiality for a particular soil; in certain districts, where the soil is stiff and moist, it grows as freely as any weed, in other soils it is perpetually going off: it is also one of those plants whose roots require to be often parted; if this be done every Autumn, and they be planted in a stiff loam, the situation somewhat moist and shady, this very desirable plant may be had to grow and blossom in perfection.
It flowers from the latter end of July to October.
Is increased by parting its roots, by cuttings of the stalk and from seed.
