Source: Begonia ‘Gryphon’ short overview
Begonia ‘Gryphon’ is an upright, cane-type begonia grown primarily for its dramatic foliage rather than abundant flowers. Large palmate leaves combine rich green coloring with silver streaks and gray markings, while the undersides and slender stems show deep orange-red tones. It performs well in bright filtered or shaded light, making it useful as a houseplant, sheltered patio container, or seasonal shade-garden accent in the United States.
Taxonomic classification
Begonia ‘Gryphon’ care guide
Light and placement
Place ‘Gryphon’ near an east-facing window, or several feet back from a bright south- or west-facing window behind a sheer curtain. It can tolerate shade but may become lanky and produce smaller, less strongly marked leaves. Harsh direct midday sun can bleach or scorch the foliage, especially through glass. Rotate the container periodically for even growth.
Watering and humidity
Water thoroughly when the upper layer of mix has begun to dry, then let excess drain completely. Keep the root zone moderately moist during active growth without leaving the pot in a saucer of water. Reduce frequency in winter or whenever growth slows. Avoid repeated wetting of the leaves and avoid cold, saturated soil, which increases the risk of stem and root rot.
Soil and growing medium
Use a loose, airy medium that combines water-holding organic matter with drainage components such as perlite, fine bark, or another porous amendment. A humus-rich loam or quality houseplant mix is suitable. The cultivar is not tied to a narrow pH range, but compacted or poorly drained soil is unsuitable and can cause rapid root and stem problems.
Feeding
Feed during active spring and summer growth with a balanced soluble fertilizer diluted to about half the label strength. Apply to already-moist soil rather than dry roots. Little or no fertilizer is needed during winter dormancy or slow growth. Flush the pot occasionally to reduce soluble-salt buildup, especially when using frequent liquid feeding.
Growth and habit
‘Gryphon’ forms upright, semi-woody cane-like stems and develops a rounded to mounded outline as it branches. Older stems can become bare at the base, particularly after winter or low-light conditions. Pinching growing tips can encourage branching, while staking may help if tall canes become top-heavy. It can persist for years when protected from cold and excessive winter moisture.
Planting and repotting
Use a sheltered, shaded site or container with excellent drainage. Plant only after frost risk has passed and soil has warmed. Keep the crown and cane bases at their original depth, firm the medium gently, and water once to settle roots. Leave enough space around the plant for airflow because crowded, humid conditions favor mildew and rot.
Repot in spring when roots have filled the container or the mix has decomposed. Move only one pot size larger and use a porous, well-drained medium. Handle the fleshy stems carefully, keep the original planting depth, and allow the surface to dry slightly before the next thorough watering.
Propagation and pruning
Propagation
RHS references propagation by seed or division. Cane begonias are also commonly increased from healthy stem cuttings, although cultivar-specific propagation instructions were not located. Take cuttings during active growth, allow wounds to dry briefly, and root them in a clean, airy medium kept lightly moist rather than wet.
Pruning
Pruning is not usually required. Remove yellow, damaged, or diseased leaves promptly with clean tools. Pinch or cut back leggy cane tips just above a node during active growth to encourage branching. Avoid heavy pruning immediately before cool, wet conditions, when fresh cuts may be more vulnerable to rot.
Overwintering
Treat ‘Gryphon’ as frost-tender. In USDA Zones 8–10, it may be overwintered outdoors only in a sheltered, protected position with sharply reduced winter watering. In colder areas, bring containers indoors before temperatures approach freezing. Provide bright indirect light, warmth, good airflow, and less frequent watering while growth is slow.
Uses
Used as a dramatic foliage accent in indoor collections, shaded patios, porch containers, mixed shade containers, and seasonal bedding displays. It is especially useful where silver foliage and reddish leaf undersides provide contrast. It is ornamental only; no culinary or medicinal use is supported.
Appearance
The most distinctive features are large asymmetrical palmate leaves with rich green surfaces, metallic silver streaking, and irregular gray markings. Leaf undersides and slender stems are deep orange-red to reddish bronze. The cane-like stems, fibrous root system, and strongly patterned foliage distinguish it from many compact bedding begonias.
Flowering
Flowering is described as rare, and commercial and garden references emphasize the foliage rather than bloom performance. A dependable flowering season, flower color, and floral form for this exact cultivar were not established in the consulted authoritative sources, so those details are left unspecified.
Pollination and visitors
The exact cultivar is reported to flower rarely, and reliable documentation of its animal flower visitors or pollinators was not found. Its value in cultivation is primarily ornamental foliage rather than a documented pollinator resource.
Diseases and pests
Diseases
Poor airflow, wet foliage, and cold saturated media can encourage powdery mildew, gray mold, stem rot, and root rot. Improve ventilation, water at the soil surface, remove affected tissue, and discard severely rotted plants. Avoid crowding and do not keep the container standing in water.
Pests
Watch for whiteflies, thrips, mites, mealybugs, aphids, caterpillars, and vine weevils, particularly on stressed or greenhouse-grown plants. Inspect leaf undersides and stem joints regularly. Isolate affected plants, remove small infestations manually, and use an appropriately labeled insecticidal soap or horticultural oil when necessary, following the product label.

Toxicity and pollen
ASPCA lists Begonia species as toxic to dogs and cats because of soluble calcium oxalates, with the underground parts identified as the most toxic. Exact toxicity data for the ‘Gryphon’ cultivar were not found, so this is a genus-level precaution rather than cultivar-specific testing. Keep stems, leaves, and especially roots or discarded cuttings away from pets and children; seek professional advice after ingestion.
- Typical season
- No reliable cultivar-specific season documented
- Pollination / pollen
- Pollen is produced only when flowers are present; cultivar-specific dispersal information is unavailable.
‘Gryphon’ rarely flowers, which limits expected pollen exposure, but rare flowering does not establish zero allergy risk. No reliable research was found on airborne pollen quantity or allergenicity for this exact cultivar. People with strong plant allergies should avoid handling flowers or dusty plant debris and wash hands afterward.
Native habitat
This is a cultivated hybrid or cultivar rather than a documented wild population. Its cane-begonia growth pattern is associated with warm, humid, frost-free environments, but ‘Gryphon’ is selected for adaptable container and indoor culture. It performs best in sheltered, organic, well-drained media with filtered light rather than exposed cold or waterlogged sites.
Interesting fact
‘Gryphon’ was introduced in 2009 by PanAmerican Seed and is also marketed under the trade name Pegasus®. The cultivar’s name refers to the mythical griffin. Its silver-marked leaves and red-orange undersides are the primary ornamental features, and the plant can survive for years with protected winter care despite often being sold as a seasonal container plant.
