Product: Impatiens walleriana

Winter hardy to USDA Zones 10-11. In St. Louis, grow as bedding annuals, container plants or houseplants. Easily grown in evenly moist, organically rich, well-drained soils in part shade to full shade. Although some varieties may be grown from seed started indoors 8-10 weeks before last frost date, numerous selections are available for purchase each year in inexpensive cell/six packs from a myriad of retail outlets ranging from nurseries to corner grocery stores. Unless a hard-to-find variety is desired, most gardeners simply purchase cell packs in spring, enjoy the long flowering season, allow the plants to succumb to frost in fall and then purchase new plants the following spring. Set out plants after last frost date. Pinch back stems of young plants to encourage branching and/or compact growth. Consider taking cuttings from unique and/or favorite plants in late summer or potting up the occasional unique plant itself in fall for overwintering. Overwintered plants need bright light but not direct sun, with reduced watering for the winter rest period.
