Begonia Shamus

Basic Information

Common Name: Begonia Shamus

Scientific Name: Begonia ‘Shamus’

Native Habitat: Hybrid (Not naturally occurring)

History / Discovery / Cultivator

Begonia ‘Shamus’ is a cultivated hybrid, meaning it doesn’t occur naturally in the wild. While the exact origins and breeder of ‘Shamus’ are often difficult to pinpoint with absolute certainty in the world of begonia hybrids, the cultivar likely originated from the efforts of begonia enthusiasts and hybridizers dedicated to expanding the genus’s horticultural appeal. Begonia hybridization is a common practice, with breeders selecting and crossing various species and cultivars to create new plants with desirable characteristics, such as unique leaf patterns, flower colors, and growth habits.

The creation of a new begonia cultivar typically involves a process of carefully selecting parent plants, pollinating one with the pollen of another, and then growing the resulting seeds. The seedlings are then evaluated for their desirable traits, and those that meet the breeder’s criteria are selected for further propagation and eventual release to the public. Unfortunately, the detailed records of many older begonia hybrids are often lost to time, making it challenging to definitively trace their lineage.

Begonias, as a genus, are native to tropical and subtropical regions around the world, including Central and South America, Africa, and Asia. These regions are home to a vast diversity of begonia species, each with its own unique characteristics. Hybridizers draw from this vast genetic pool to create new and exciting cultivars like ‘Shamus’. The popularity of begonias as houseplants has driven a constant demand for novel and visually striking varieties, fueling the work of dedicated breeders.

The ‘Shamus’ cultivar, while lacking a precise documented history, likely emerged from a focused breeding program aiming for specific ornamental traits. It probably took place many years ago, explaining the lack of detailed records. Characteristics like the leaf coloration, texture, and overall plant form would have been key selection criteria. Its success and continued propagation suggest it possesses qualities that appeal to begonia collectors and enthusiasts.

The begonia world is filled with countless hybrids, each with its own story, even if that story is partially shrouded in mystery. ‘Shamus’ stands as a testament to the ongoing creativity and dedication within the begonia community, a visual embodiment of the continuous pursuit of horticultural innovation. It reflects the broader story of plant domestication and the human fascination with creating new and beautiful forms of plant life through selective breeding. Further research into older begonia society records or horticultural journals might one day reveal more about its specific origins, but for now, it remains a beautiful begonia hybrid with an intriguing, albeit somewhat elusive, past.

Plant Care Summary

Botanical Insights

Adaptations

Begonias, in general, have adapted to thrive in the understory of tropical forests. Their tolerance for lower light conditions is a key adaptation. Rex begonias, which ‘Shamus’ is likely related to, often have striking leaf patterns that may serve as camouflage in the dappled light of the forest floor or even mimic the appearance of less palatable plants. Begonias have also evolved succulent-like stems and leaves in some cases, allowing them to store water and tolerate periods of drought. Their fibrous root systems are adapted for absorbing nutrients from the rich organic matter found in forest soils. In cultivation, these adaptations translate into a need for well-draining soil and protection from intense sunlight.

Propagation Methods

Begonia ‘Shamus’ can be propagated through several methods:

• Stem Cuttings: Take a stem cutting with at least one node and place it in water or directly into moist potting mix.
• Leaf Cuttings: Rex begonias, in particular, can be propagated by cutting a leaf into wedges, each containing a vein, and placing them on moist potting mix under high humidity.
• Division: Mature plants can be divided at the root ball, ensuring each division has healthy roots and leaves.

Toxicology

Begonias contain insoluble calcium oxalates. If ingested by humans or pets (especially cats and dogs), these crystals can cause significant oral irritation. Symptoms include excessive drooling, pawing at the mouth, vomiting, and difficulty swallowing. While rarely life-threatening, ingestion can be very uncomfortable. It is important to keep begonias out of reach of children and pets. Contact your veterinarian or physician immediately if ingestion is suspected.

Common Problems

Pests:

• Mealybugs
• Spider mites
• Aphids

Diseases:

• Powdery mildew
• Botrytis blight
• Root rot

Other:

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

Rarity & Value

Rarity:

Begonia ‘Shamus’ is not considered particularly rare, as it’s been around for a while and is available in many nurseries and online retailers. However, particularly well-grown specimens with vibrant colors and healthy foliage can command a higher price. Sometimes older cultivars that cycle in and out of mainstream availability can become less common, temporarily increasing their value.

Value:

The value of Begonia ‘Shamus’ is influenced by factors such as:

• Size and Maturity: Larger, more mature plants typically have a higher value.
• Leaf Quality: The vibrancy and pattern of the leaves are critical. Well-colored and patterned leaves will increase the value.
• Overall Health: A healthy plant free from pests and diseases is more valuable.
• Pot and Presentation: A plant attractively potted can also increase its appeal and perceived value.
• Current Trends: Demand for certain types of begonias fluctuates with trends, which can affect pricing.
