Lenore Olivier Begonia

Basic Information

Common Name: Lenore Olivier Begonia

Scientific Name: Begonia ‘Lenore Olivier’

Native Habitat: Hybrid; Origin uncertain.

History / Discovery / Cultivator

Begonia ‘Lenore Olivier’ is a captivating hybrid begonia, highly prized for its stunning foliage. Unlike species found in the wild with known native habitats, ‘Lenore Olivier’ is a cultivated variety, which means it was specifically bred by horticulturists for its desirable characteristics. Pinpointing the exact origins and the individual or institution responsible for its creation is proving difficult, a relatively common occurrence with many hybrid begonias. The records are often either lost to time or proprietary.

What we do know is that it belongs to the Rex begonia group, renowned for their flamboyant and intricately patterned leaves. These begonias, with their diverse colors, textures, and shapes, have been a source of fascination for plant collectors and breeders for over a century. ‘Lenore Olivier’ undoubtedly owes its existence to the extensive breeding programs that have sought to push the boundaries of what’s possible within the Rex begonia lineage.

The “Rex” designation refers to Begonia rex, a species native to Assam, India. This species served as a foundational parent for many of the Rex hybrids we see today. While the exact parentage of ‘Lenore Olivier’ remains somewhat mysterious, it’s reasonable to assume that Begonia rex or other closely related species contributed to its genetic makeup.

The popularity of ‘Lenore Olivier’ likely stems from its exceptional beauty and relatively manageable care requirements compared to some other Rex begonias. Its shimmering, almost iridescent leaves and unique coloration, often featuring swirls of silver, pink, and green, make it a standout addition to any plant collection. The name “Lenore Olivier” itself likely refers to either the breeder who created the hybrid or someone who significantly contributed to its popularization. It’s common practice for hybrid plants to be named after individuals as a tribute.

The cultivation of Begonia ‘Lenore Olivier’ aligns with the general practices used for other Rex begonias. It thrives in bright, indirect light, high humidity, and well-draining soil. The plant’s adaptability to indoor conditions has further contributed to its popularity as a houseplant. Its ability to bring a touch of the exotic into the home has solidified its place as a sought-after specimen among plant enthusiasts.

In conclusion, while the complete history of Begonia ‘Lenore Olivier’ remains somewhat elusive, its beauty and relative ease of care have cemented its place in the world of cultivated plants. It stands as a testament to the art and science of plant breeding, demonstrating the remarkable diversity and aesthetic appeal that can be achieved through careful hybridization. Its continuing popularity is a fitting tribute to the (likely) skillful horticulturalist who first envisioned and created this stunning variety. Further research into the begonia societies and historic breeding records could potentially reveal the fascinating details behind its creation, solidifying its place in the botanical record.

Plant Care Summary

Botanical Insights

Adaptations

Begonia ‘Lenore Olivier’, like other Rex begonias, exhibits several adaptations that make it successful as a houseplant. Its large, intricately patterned leaves are adapted to capture as much light as possible in the often-dim understory environments it imitates indoors. The rhizomatous growth habit allows it to spread horizontally, forming new shoots and roots along the surface of the soil. This adaptation enables it to quickly colonize available space. The plant’s sensitivity to overwatering is also an adaptation, preventing root rot in humid environments where fungal diseases are prevalent. Rex begonias are particularly susceptible to fungal problems if kept too wet. Its textured leaves may also deter some pests.

Propagation Methods

Begonia ‘Lenore Olivier’ can be effectively propagated through several methods:

• Leaf Cuttings: This is a common method for Rex begonias. Cut a leaf into wedges, ensuring each wedge has a vein. Place the wedges on a moist growing medium (e.g., peat moss or vermiculite) and cover with a plastic dome to maintain humidity. Roots will develop from the cut edges of the veins.
• Rhizome Cuttings: As a rhizomatous begonia, pieces of the rhizome can be cut and planted to create new plants. Ensure each section has at least one node (growth point).
• Stem Cuttings: While less common, stem cuttings can also be successful. Take a cutting with several leaves and place it in water or a moist growing medium until roots develop.

Toxicology

Begonia ‘Lenore Olivier’ is considered toxic to both humans and pets, particularly cats and dogs. The primary toxic components are soluble calcium oxalates. When 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 airways can occur, although this is rare. If ingestion is suspected, it is crucial to immediately contact a veterinarian or poison control center. It is best to keep this plant out of reach of children and pets.

Common Problems

Pests:

• Mealybugs
• Spider mites
• Aphids

Diseases:

• Powdery mildew
• Root rot
• Botrytis blight

Other:

• Leaf yellowing: Overwatering or nutrient deficiency.
• Browning leaf edges: Low humidity or inconsistent watering.
• Leaf drop: Sudden temperature changes or drafts.

Rarity & Value

Rarity:

Begonia ‘Lenore Olivier’, while not exceedingly rare, can sometimes be less readily available than more common Rex begonia cultivars. Its stunning coloration and specific patterning contribute to its desirability, which can occasionally drive up demand. The availability can fluctuate depending on the propagation efforts of nurseries specializing in begonias. The difficulty in tracing its specific parentage also makes it less amenable to large-scale production.

Value:

The value of a Begonia ‘Lenore Olivier’ specimen is influenced by several factors. The size of the plant, the vibrancy and uniqueness of its leaf patterns, and its overall health all play a role. A mature plant with well-defined colors and patterns will generally command a higher price. Plants with particularly unusual or striking variegation are especially prized by collectors. Furthermore, the reputation of the seller and the plant’s provenance (e.g., whether it originated from a reputable nursery) can also impact its value. Finally, current trends in the collector market can cause fluctuations in the perceived value of even relatively common plants.
