Wax Begonia (Begonia × Semperflorens-Cultorum ‘Harmony Scarlet’)

Care and Maintenance

Tender perennial that is winter hardy to USDA Zones 10-1 In St. Louis, it is grown as an annual. It is noted for its tolerance to hot and humid summers. It is easily grown in average to moderately fertile, moist, well-drained soils in full sun to part shade. Prefers sun-dappled, part shade and a good mulch in hot summer climates such as St. Louis. Bronze-leaved varieties are more tolerant of full sun. Plants tolerate considerable shade, but are generally less floriferous with less sun. Plants are best with consistent moisture throughout the growing season, but tolerate periods of drought due to their thick and waxy leaves which help minimize water loss in hot weather. Start seeds indoors 6-8 weeks before last frost date, purchase starter plants or take cuttings from overwintered plants. Set plants out after last frost date. Space plants well (8” for dwarfs and 12” for taller ones) to promote good air circulation and to reduce potential fungal disease problems. Container plants may be cut back in fall and overwintered indoors a cool location with reduced watering. Propagation from seed can be difficult due to the small size of the seed, and seed should not be sown directly in the garden.
