Lucerna Begonia

Basic Information

Common Name: Lucerna Begonia
Scientific Name: Begonia ‘Lucerna’
Native Habitat: Hybrid, origin uncertain, likely South American ancestry.

History / Discovery / Cultivator

Begonia ‘Lucerna’ is a stunning hybrid cane-like begonia, beloved for its impressive size, striking foliage, and profusion of flowers. While its exact origins remain somewhat shrouded in mystery, its cultivated history is rich and rewarding. Cane-like begonias, in general, boast a lineage tracing back primarily to South America, particularly Brazil, where many of their wild ancestors thrive in the shaded understories of tropical forests. These ancestors contributed significantly to the characteristics we admire in ‘Lucerna’, such as its upright growth habit, segmented stems, and resilience.

The history of ‘Lucerna’ is intertwined with the broader development of begonia hybridization during the 19th and early 20th centuries. During this period, horticulturalists were captivated by the potential of begonias and actively sought to create new and improved varieties. They crossbred different species and cultivars, selecting for desirable traits like flower color, leaf shape, and overall vigor. While it’s difficult to pinpoint the exact person responsible for creating ‘Lucerna’, it is likely the result of a deliberate cross, rather than spontaneous mutation. It is also very unlikely that ‘Lucerna’ occurred in the wild, due to its complex genetic makeup.

Cane-like begonias, like ‘Lucerna’, became highly fashionable as houseplants, particularly in Victorian-era conservatories. Their architectural presence and ability to tolerate indoor conditions made them a perfect fit for the grand homes and plant collections of the time. ‘Lucerna’ would have been shared among avid begonia collectors, appearing in catalogs of nurseries and botanical gardens. Propagation through stem cuttings helped to ensure the plant spread through the horticultural world. The popularity of the ‘Lucerna’ Begonia is partially due to the overall hardiness of cane-like varieties, but more so because of its uniquely spectacular display. Its elegant stature, combined with silver spots, makes it a highly desirable cultivar, and its robust nature ensures the plant does well, even in the hands of a novice caretaker.

The lasting appeal of Begonia ‘Lucerna’ can be attributed to its dramatic appearance and relatively easy care, combined with a deep history of cultivation across two centuries. It stands as a testament to the art and science of plant breeding, a beautiful example of the possibilities that emerge when different species are combined in a single plant. It’s a plant with a past, that can add a distinguished presence to any collection or home.

Plant Care Summary

Botanical Insights

Adaptations

Begonia ‘Lucerna’ exhibits several adaptations that contribute to its survival and success as a cultivated plant. Its cane-like stems provide structural support, allowing it to grow tall and reach for light in its natural habitat (or as a houseplant). The asymmetrically shaped leaves, a common characteristic of begonias, maximize light capture. The leaf shape helps to distribute sunlight more evenly across the leaf surface. The plant’s tolerance of moderate shade and humidity reflects its origins in the understory of tropical forests. The showy flowers, while primarily for attracting pollinators in its ancestral forms, serve an aesthetic function in cultivation, making it a desirable houseplant. Its ability to propagate easily from stem cuttings makes it well-suited for cultivation and distribution. The silver spots on the leaves may act as a deterrent to herbivorous insects.

Propagation Methods

Begonia ‘Lucerna’ is readily propagated by several methods:
* Stem Cuttings: The most common and reliable method. Take a cutting from a healthy stem, ensuring it has at least one node. Remove the lower leaves and place the cutting in water or directly into moist potting mix. Roots will typically develop within a few weeks.
* Leaf Cuttings: While less reliable than stem cuttings, leaf cuttings can also be used. Cut a leaf into sections, making sure each section includes a vein. Place the sections on top of moist potting mix and cover with a plastic dome or bag to maintain humidity.
* Division: For larger, well-established plants, division can be an option. Carefully separate the rhizome into sections, ensuring each section has roots and stems. Pot each section separately.

Toxicology

Begonia ‘Lucerna’, like many other begonias, contains soluble calcium oxalates. These crystals are irritating to the mouth and throat if ingested. In humans, ingestion can cause temporary oral irritation, drooling, and difficulty swallowing. In pets, such as cats and dogs, ingestion can lead to similar symptoms, including excessive drooling, vomiting, and pawing at the mouth. While serious complications are rare, it’s best to keep this plant out of reach of children and pets. If ingestion is suspected, rinse the mouth with water and contact a veterinarian or poison control center for further guidance.

Common Problems

Pests:

• Mealybugs
• Spider mites
• Aphids

Diseases:

• Root rot (due to overwatering)
• Powdery mildew
• Bacterial leaf spot

Other:

• Leaf yellowing (often caused by overwatering or nutrient deficiency)
• Browning leaf tips (usually caused by low humidity or dry air)
• Leggy growth (insufficient light)

Rarity & Value

Rarity:

Begonia ‘Lucerna’ is not considered a rare plant. It is a well-established and widely cultivated hybrid. However, large, mature specimens with well-developed canes and abundant blooms can command a higher price. Plants with particularly striking silver spotting can also be more sought after.

Value:

Several factors affect the market value of a Begonia ‘Lucerna’ specimen:
* Size: Larger plants, particularly those with multiple established canes, are generally more valuable.
* Maturity: Mature plants that flower regularly command higher prices.
* Overall Health: A healthy plant with vibrant foliage and strong growth will be more valuable than a stressed or unhealthy one.
* Presentation: Well-presented plants in attractive pots will generally fetch a higher price.
* Demand: As with any plant, demand can fluctuate based on current trends and collector interest.
