Thurstonii Begonia
Basic Information
Common Name: Thurstonii Begonia
Scientific Name: Begonia ‘Thurstonii’
Native Habitat: Hybrid, origin uncertain.
History / Discovery / Cultivator
Begonia ‘Thurstonii’ is a hybrid begonia, and as such, its precise history is somewhat shrouded in mystery. Unlike naturally occurring species with defined geographical origins, hybrids are created through intentional cross-pollination by plant breeders. This means its lineage can be traced to specific parent plants, but its ultimate “origin” is the greenhouse or garden where it was first developed.
The ‘Thurstonii’ cultivar is believed to be quite old, potentially dating back to the late 19th or early 20th century. The exact breeder and circumstances of its creation are not widely documented, contributing to its enigmatic past. Its name, ‘Thurstonii,’ strongly suggests it was either bred by a person named Thurston or named in their honor. Horticultural practices during that era often involved naming new cultivars after prominent gardeners, botanists, or patrons of horticulture. However, definitive records confirming the “who” and “when” remain elusive.
The plant’s characteristics suggest potential parentage involving other well-known begonias of the time. It exhibits features common in some cane-like begonias, known for their upright growth habit and distinctive stems. The thick, textured leaves with their subtle coloration hint at the possibility of rex begonia influence in its background. Rex begonias are prized for their intricate leaf patterns and colors. The hybrid vigor resulting from this potential combination leads to the vigorous growth that ‘Thurstonii’ displays.
Despite the lack of concrete information about its specific origins, Begonia ‘Thurstonii’ has enjoyed enduring popularity among begonia enthusiasts. Its relatively easy care compared to some other begonias and its attractive appearance have contributed to its longevity in cultivation. It’s often passed down through generations of gardeners, solidifying its place as a beloved heirloom plant. While perhaps not considered extremely rare, it is also not as commercially ubiquitous as some newer begonia cultivars, making it a sought-after treasure for collectors seeking plants with a touch of history. Its resilience and lasting appeal are a testament to the skill of the unknown breeder who first created this remarkable hybrid. Its continued presence in gardens and homes is a tribute to their artistry.
Plant Care Summary
| Category | General Requirement | Notes |
|---|---|---|
| Light | Bright Indirect | Avoid direct sunlight which can scorch the leaves. |
| Water | Moderate | Allow the top inch of soil to dry out before watering thoroughly. Avoid overwatering. |
| Humidity | Moderate to High | Prefers humidity above 50%. Use a humidifier or pebble tray if needed. |
| Temp. Range | 65-80°F (18-27°C) | Avoid sudden temperature fluctuations and drafts. |
| Soil Type | Well-draining | Use a well-draining potting mix, such as one formulated for begonias or African violets. |
| Fertilizer | Balanced liquid feed | Fertilize monthly during the growing season (spring/summer) with a diluted balanced liquid fertilizer. |
| Toxicity | Toxic to Pets | Contains soluble oxalates, which can cause oral irritation, excessive drooling, vomiting, and difficulty swallowing if ingested. |
Botanical Insights
Adaptations
Begonia ‘Thurstonii’, being a hybrid, doesn’t have adaptations in the same way as a wild species. However, its combination of traits from cane and rex begonia ancestry contributes to its success as a houseplant. Its upright, cane-like growth allows it to maximize light capture in potentially shaded environments. Its relatively thick leaves are somewhat drought-tolerant, providing a buffer against inconsistent watering. The textured leaf surface may help trap moisture from the air. Furthermore, its tolerance of indoor conditions makes it a resilient and adaptable houseplant.
Propagation Methods
The most common and effective propagation method for Begonia ‘Thurstonii’ is stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Place the cutting in water or directly into a well-draining potting mix. Keep the cutting moist and in a humid environment until roots develop. Leaf cuttings can also be successful, though they take longer. Division of larger, established plants is also possible.
Toxicology
Begonia ‘Thurstonii’ contains soluble calcium oxalates. If ingested, these crystals can cause intense burning and irritation of the mouth, tongue, and throat. Symptoms in humans include excessive drooling, difficulty swallowing, and a burning sensation. In pets (cats and dogs particularly), similar symptoms are observed, including vomiting. While rarely life-threatening, ingestion can be very uncomfortable and require veterinary or medical attention to manage the symptoms. Keep this plant out of reach of children and pets.
Common Problems
Pests:
- Mealybugs
- Spider mites
- Aphids
Diseases:
- Powdery mildew
- Botrytis blight (grey mold)
- Root rot (from overwatering)
Other:
- Leaf yellowing: Overwatering or nutrient deficiency.
- Brown leaf tips: Low humidity or inconsistent watering.
- Leggy growth: Insufficient light.
Rarity & Value
Rarity:
Begonia ‘Thurstonii’ is not exceptionally rare but isn’t as commonly available as some newer hybrids. Its longevity in cultivation and potential for being passed down through generations mean it can be found but might require searching specialty nurseries or online plant communities. Its lack of recent large-scale commercial propagation contributes to its somewhat limited availability.
Value:
The value of Begonia ‘Thurstonii’ is influenced by several factors. Larger, more mature specimens with well-established growth command higher prices. Healthy plants free from pests and diseases are also more valuable. While variegation isn’t a characteristic of the species, particularly attractive specimens may fetch a slightly higher price. The plant’s overall health and presentation are critical determinants of value.
