Begonia Evening Glow

Basic Information

Common Name: Begonia Evening Glow

Scientific Name: Begonia ‘Evening Glow’

Native Habitat: Hybrid cultivar, origin unknown.

History / Discovery / Cultivator

Begonia ‘Evening Glow’ is a captivating hybrid begonia prized for its striking foliage. Unfortunately, tracing the exact origins and the cultivator responsible for this specific cultivar proves difficult, as detailed records are not readily available in horticultural databases or historical accounts. The lack of specific documentation surrounding its creation is not uncommon with hybrid plants, especially those developed many years ago, or by smaller, independent breeders.

However, we can infer some likely influences based on its characteristics. ‘Evening Glow’ clearly belongs to the rhizomatous begonia group, which are known for their diverse leaf shapes, textures, and colors. Rhizomatous begonias, native to tropical and subtropical regions worldwide, have been cultivated for centuries, offering a rich genetic pool for hybridization. It is plausible that ‘Evening Glow’ emerged from intentional or even accidental cross-pollination between various rhizomatous begonia species or existing cultivars.

The “Evening Glow” name itself suggests the plant’s defining feature: its luminous, almost iridescent foliage. The leaves often display a blend of pink, silver, and green hues, particularly when exposed to bright, indirect light, which enhances the perceived “glow.” This distinctive coloration would have undoubtedly been a primary focus for the hybridizer.

The rise in popularity of begonias, particularly rhizomatous varieties, as houseplants in the latter half of the 20th century likely contributed to the development and distribution of cultivars like ‘Evening Glow.’ Horticultural enthusiasts and nurseries actively sought to create and introduce new and visually appealing begonias to meet the growing demand. The relative ease of propagation through rhizome divisions further facilitated the spread of such cultivars.

While the specific individual or nursery responsible for ‘Evening Glow’ remains shrouded in mystery, its enduring popularity speaks volumes about its unique beauty and relatively easy care, ensuring its continued presence in collections and homes worldwide. The begonia world is filled with unnamed heroes who have undoubtedly helped to provide us with the species that we have today. Perhaps sometime in the future the cultivator of this incredible species will be uncovered to be appreciated.

Plant Care Summary

Botanical Insights

Adaptations

Begonia ‘Evening Glow’, as a rhizomatous begonia, exhibits several interesting adaptations. The rhizome itself is a modified stem that grows horizontally, either on or just below the soil surface. This allows the plant to spread vegetatively and store water and nutrients, enabling it to survive periods of drought. The striking leaf coloration, while aesthetically pleasing to humans, may also serve as a form of camouflage in its natural habitat, or even as a deterrent to herbivores. The somewhat succulent leaves also help the plant store water, making it more tolerant of slightly drier conditions.

Propagation Methods

‘Evening Glow’ is most commonly propagated through rhizome cuttings or leaf cuttings. Rhizome cuttings involve dividing the rhizome into sections, each with at least one leaf node, and planting them in a well-draining potting mix. Leaf cuttings can be taken by cutting a leaf into wedges, each containing a vein, and placing them on a moist substrate under high humidity. Both methods benefit from bottom heat and high humidity to encourage root development. Stem cuttings are less common but can also be successful.

Toxicology

Begonia ‘Evening Glow’ 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. Symptoms in pets may include excessive drooling, vomiting, and difficulty swallowing. In severe cases, swelling of the upper airway may occur, making it difficult to breathe. While usually not life-threatening, it’s essential to keep this plant out of reach of children and pets. Seek veterinary attention if a pet ingests a significant amount of the plant.

Common Problems

Pests:

• Mealybugs
• Spider mites
• Aphids

Diseases:

• Powdery mildew
• Botrytis blight (grey mold)
• Root rot (caused by overwatering)

Other:

• Leaf yellowing: Often caused by overwatering or nutrient deficiency.
• Browning leaf tips: Typically due to low humidity or inconsistent watering.
• Leggy growth: Insufficient light can cause the plant to stretch and become leggy.

Rarity & Value

Rarity:

While not exceptionally rare, Begonia ‘Evening Glow’ can be somewhat uncommon compared to more widely available begonia varieties. This can be attributed to factors such as slower propagation rates than some other begonias, specific cultivation requirements that might make it less appealing to novice growers, and periodic fluctuations in market demand. Its distinctive coloration makes it a sought-after plant for collectors and enthusiasts, which can contribute to its perceived rarity in certain regions or markets.

Value:

The value of a Begonia ‘Evening Glow’ specimen is influenced by several factors. Size is a primary determinant, with larger, more mature plants generally commanding higher prices. The intensity and stability of the leaf coloration, particularly the “glow” effect, play a significant role; plants with vibrant and consistent coloration are more valuable. Overall plant health and the absence of pests or diseases are also crucial. Current trends in the plant collecting community can influence demand, with popular plants experiencing price increases. Rarity (as mentioned above) also contributes to value.
