Corallina de Lucerna Begonia

Basic Information

Common Name: Corallina de Lucerna Begonia

Scientific Name: Begonia ‘Corallina de Lucerna’

Native Habitat: Hybrid cultivar; Origins traced to France

History / Discovery / Cultivator

The Begonia ‘Corallina de Lucerna’ is a striking example of the cane-like begonias, a group renowned for their upright growth habit, attractive foliage, and clusters of delicate flowers. Its origin is rooted in hybridization, a process where plant breeders combine the desirable traits of different species or cultivars to create something new and improved. While the exact parentage of ‘Corallina de Lucerna’ isn’t always precisely documented (as is common with older cultivars), it’s generally accepted that it derives from crosses involving Begonia coccinea and other similar cane-like species.

The likely origin of this particular begonia lies in France, dating back to the late 19th or early 20th century. During this period, European horticulture experienced a boom in begonia cultivation, with numerous breeders actively developing new hybrids. The “de Lucerna” part of the name hints at its potential association with a specific garden or breeder located in or near Lucerne, Switzerland, although definitive proof linking it to that specific location remains elusive. It’s possible the name simply alludes to the beauty and luminescence associated with Lucerne, a picturesque city known for its stunning lake and surrounding landscape.

These early begonia breeders were often driven by a desire to create plants with enhanced ornamental qualities, such as more vibrant flower colors, more interestingly shaped leaves, and greater disease resistance. ‘Corallina de Lucerna’ exemplifies these goals. Its tall, cane-like stems create a dramatic silhouette, while its silvery-spotted, dark green leaves add visual interest even when the plant isn’t in bloom. The clusters of coral-red or pink flowers are a delightful bonus, appearing periodically throughout the year under suitable growing conditions.

Unlike some plants with a clear “discoverer” or “cultivator,” ‘Corallina de Lucerna’ emerged more gradually as a popular cultivar, likely through distribution by various nurseries and propagators. Over time, it gained a following among begonia enthusiasts and became a staple in collections. Its relative ease of propagation (through stem cuttings) and its adaptability to indoor growing conditions contributed to its widespread availability.

While the specific details of its initial development might remain shrouded in horticultural history, the enduring popularity of ‘Corallina de Lucerna’ speaks to the skill and vision of the early begonia breeders who paved the way for its creation. It serves as a testament to the ongoing pursuit of beauty and innovation in the world of cultivated plants, a timeless reminder that even the most familiar varieties often have fascinating stories to tell. This variety showcases how begonia hybridizing greatly contributed to the diversity of plants available today.

Plant Care Summary

Botanical Insights

Adaptations

Begonia ‘Corallina de Lucerna’ exhibits several adaptations that contribute to its success as both a cultivated plant and a reflection of its cane-like begonia heritage. Its upright, cane-like stems allow it to reach for light in shaded environments, mimicking its natural habitat under the canopy of tropical forests. The silvery spots on its leaves are believed to provide some protection against intense sunlight, acting as a form of natural sunscreen. The somewhat succulent stems and leaves also provide some drought tolerance. As a hybrid, this plant has been selected to thrive in indoor settings.

Propagation Methods

‘Corallina de Lucerna’ is most commonly propagated via stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. The cutting can then be rooted in water or directly in a well-draining potting mix. Rooting hormone can improve success rates. Leaf cuttings are also possible but tend to be slower and less reliable. Division of larger plants is possible, but stem cuttings are the preferred method.

Toxicology

Begonia ‘Corallina de Lucerna’ contains soluble calcium oxalates, which are toxic to both humans and pets. If ingested, these oxalates can cause intense burning and irritation of the mouth, tongue, and throat. In humans, this can lead to drooling, difficulty swallowing, and vomiting. In pets (particularly cats and dogs), symptoms can include excessive drooling, pawing at the face, and loss of appetite. While ingestion is rarely fatal, it can be extremely uncomfortable, and prompt veterinary attention is recommended for pets. Keep this plant out of reach of children and pets.

Common Problems

Pests:

• Mealybugs
• Spider mites
• Aphids

Diseases:

• Powdery mildew
• Root rot
• Botrytis blight (Gray mold)

Other:

• Leaf yellowing: Often caused by overwatering or nutrient deficiency.
• Browning leaf tips: Can be caused by low humidity or excessive fertilizer salts.
• Leggy growth: Insufficient light can cause stems to become long and weak.

Rarity & Value

Rarity:

While ‘Corallina de Lucerna’ is a relatively well-established cultivar, its rarity can fluctuate based on current trends and availability. It is not exceptionally rare, but older, well-grown specimens with established canes can be more difficult to find. The resurgence of interest in classic begonias can also contribute to increased demand and, consequently, a temporary increase in its perceived rarity.

Value:

The value of a ‘Corallina de Lucerna’ begonia depends on several factors. Larger, more mature plants with multiple canes command higher prices. The overall health and vigor of the plant, including the quality of the foliage and the presence of flowers, also play a significant role. Additionally, the pot and presentation can affect the perceived value, as can current market trends and the reputation of the seller. A well-grown specimen in a decorative pot will typically fetch a higher price than a smaller, less established plant.
