This genus includes the well-known Balsam and the free-flowering Impatiens Sultani from Zanzibar.
The Balsam delights in a rich light soil and a warm sheltered situation away from cold winds and fog. Being an annual, it is raised only from seeds. The seeds should be sown in a hotbed or warm greenhouse and covered very lightly with finely-sifted sandy leaf-mold, March being a good month for the planting of the seeds which germinate in a few days. The seedlings should be pricked out, as soon as they are large enough to be handled, and planted three inches apart in pans or boxes; as soon as they fill the space in the boxes, they should be planted out where they are to bloom, or given more root-room so that their growth may not receive any check, otherwise their stems will become stunted and the flowers small and colorless. After planting them out of doors, give them a good watering and mulch them with well-decayed manure, giving them copious waterings at least twice a week.
Impatiens Sultani, being a perennial, in addition to being easily raised from seeds may be increased by cuttings, taken, in March or April, from tops of the young growths, inserted in sandy leaf-mold and placed in a hotbed or warm greenhouse where they will root in about ten days and be ready for potting. Impatiens Sultani makes an elegant pot plant, useful for decorating the greenhouse or for placing on a warm veranda.
