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 Llossoms, which renders it a suitable plant to ornament the shrubbery, or a 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.
This is a hardy plant, of ready growth: will bear the smoke of London better than many others; if it continues in the same spot for a great number of years, the blossoms are apt to become single.
The single sort, according to Morison, was introduced before 1699 by Lord Lemster. Ait. Kew.
