This charming North American hardy herbaceous perennial has found its way into the markets and florists' shops, and even among street sellers of late years. It grows about 6 in. high, and produces fine masses of large roundish green leaves which become beautifully bronzed or crimsoned in autumn, and are, therefore, valuable as a backing for cut flowers of a lighter colour. The plants flourish in peaty soil, or in a garden soil well enriched with decayed manure, and, being easily grown and lasting for years, may be regarded as a fairly lucrative if not extensive crop.
