Description

‘Bossa Nova® Yellow’ is an annual plant that forms a lush, mounded shape in its early stages. Eventually, it develops a cascading habit that makes it perfect for hanging baskets and container gardening. The plant grows to a height of 12-16 inches and spreads 16-20 inches, with trailing stems that display soft yellow, pendulous flowers. These blooms contrast beautifully with the deep green, thin foliage, creating a visually appealing display. The flowers, which measure 2-3 inches, are prolific and resemble colorful jewels dangling among the leaves. This begonia’s unique characteristic is its drought tolerance, uncommon among most begonias, and its resilience in full sun to part shade environments.

Care Instructions for Begonia boliviensis ‘Bossa Nova® Yellow’:

Begonia ‘Bossa Nova® Yellow’ is relatively easy to care for, making it suitable for novice and experienced gardeners. Here are some key care instructions:

Light Requirements: This begonia thrives in part shade to full shade, although it can tolerate full sun if kept adequately moist. For optimal blooming, provide it with 4-6 hours of sunlight daily.
Watering: Keep the soil moist but not soggy. Allow the soil to dry to the touch between waterings to prevent root rot. During the growing season, water regularly but reduces the frequency in cooler months.
Soil: Plant in light, rich, moist, and well-drained soil. Ensure good air circulation and protect the plant from strong winds.
Feeding: Fertilize regularly with a balanced fertilizer to encourage continuous blooming—a slow-release, general-purpose fertilizer applied in the spring works best.
Pruning: Deadheading is unnecessary for this begonia, but trimming the plant back can help maintain its shape and encourage more vigorous growth.
Winter Care: In zones cooler than USDA hardiness zones 7-10, dig up the tubers before the first frost and store them in a cool, dry place over the winter to replant in the spring.

Propagation

Propagation of Begonia ‘Bossa Nova® Yellow’ is typically done through cuttings or by dividing the tubers. Here’s how you can propagate it:

Cuttings: Take healthy stem cuttings in the spring or early summer. Plant the cuttings in a moist, well-drained potting mix and place them in a warm, bright location. Roots should develop in a few weeks.
Tubers: At the end of the growing season, carefully dig up the tubers, let them dry, and store them in a cool, dry place. In the spring, replant the tubers in fresh soil.

Pest and Disease Management

While Begonia boliviensis ‘Bossa Nova® Yellow’ is generally resilient, it can be susceptible to common pests such as aphids, spider mites, and whiteflies.
