The Helianthus multiflorus, a native of North-America, is a hardy perennial herbaceous plant, arising usually to the height of five or six feet, and producing a great number of large yellow shewy blossoms, which renders it a suitable plant to ornament the shrubbery or garden of large extent; the variety with double flowers is the one most commonly cultivated, and this we find in almost every garden: it flowers from July to September, and is propagated by parting its roots in autumn.
