Big Series Begonia Begonia x benaratensis Big Series

Hybrid wax begonia, introduced by Benery Seed, is a seed-grown plant derived from hybridizing angel wing begonia with fibrous F1 begonia hybrids. It is in the Begoniaceae (Begonia) family.

Begoniaceae is a large, flowering plant family, the name of which honors Michael Begon (1638-1710), Governor of French Canada, and includes about 1500 different species and hundreds of hybrids. Mature begonia plants range in size from a few inches high to over 12 inches high, and the flowers, foliage colors, and sizes are very diverse.

Hybrid wax begonias are compact, bushy, and mounded with fibrous roots, fleshy stems, tough, waxy, dark green to bronze leaves, and loose clusters (cymes) of single or double flowers in shades of white, pink, or red plus bicolor versions. They are vigorous plants that flower reliably throughout the growing season (May to October). Big Series is noted for its early bloom, large flowers, and vigorous habit. The plants are generally low maintenance and grow 12 to 18 inches high with a similar spread.

Noted for its tolerance to hot and humid summers, Big Series begonia grows well in average to moderately fertile, moist, well-drained soils in full sun to part shade, preferring sun-dappled part shade. Bronze-leaved varieties are more tolerant of full sun. Best results will be obtained by providing consistent moisture throughout the growing season. The plant will tolerate periods of drought, as the thick and waxy leaves help minimize water loss in hot weather. A frost-sensitive perennial, it is typically grown to be used as an annual in all but USDA zones 10a to 11b. If grown in a container, you can cut back the plant in the fall and overwinter it indoors in a cool location with reduced watering.

Growing from seed can be difficult; however, you can start the small seeds indoors 6 to 8 weeks before the last frost date. Do not sow seeds directly in the garden. Alternatively, you can purchase starter plants or take cuttings from overwintered plants. Set plants out after the last frost date. Space the plants 12 to 15 inches apart to promote good air circulation and to reduce potential fungal disease problems. 

These begonias are excellent candidates for a border, mass planting, containers, hanging baskets, and as a houseplant.  

Insects, Diseases, and Other Plant Problems: Watch for mealybugs and thrips. Susceptible to bacterial leaf spot, powdery mildew, blight, and stem/crown rots.
