Begonia sp. U577 – Deep Tones, Rippled Texture, Rhizomatous Elegance


Begonia U577 – Leaf Texture, Color Shifts and Compact Growth Habit


Begonia sp. U577 is an unregistered rhizomatous hybrid prized for its rich, dark foliage and tightly curled form. The leaves are rounded to oval with a distinctive ripple around the edges and prominent veins that draw the eye inward. Depending on light and humidity, the color ranges from deep olive to burgundy-black, often with subtle metallic undertones that change throughout the day.
This Begonia stays low and wide, growing slowly from a creeping rhizome. The overlapping foliage forms a compact, textured mound — ideal for display in shaded spaces, terrariums, or cabinets where its color and detail can shine up close.

Background origin and natural preferences


Begonia sp. U577 likely traces its lineage to Southeast Asian or Central American rhizomatous species, adapted to moist forest floors under canopy shade. In the wild, such Begonias grow in constantly warm, humid environments with rich organic substrate and consistent moisture. Indoors, this cultivar responds well to similar conditions — stable temperatures between 18–24 °C, high humidity, and bright, filtered light.
Like other Begonias, it is toxic to pets and humans if ingested due to calcium oxalate crystals.


Begonia U577 care instructions


 
Light: Bright, indirect light; avoid direct sun that can scorch leaves
 
Water: Water when the top 2–3 cm of soil is dry; don’t let roots stay soggy
 
Humidity: Prefers 60–80%; best suited for enclosed spaces or use a room humidifier
 
Temperature: Ideal range is 18–24 °C; avoid cold spots or sudden drafts
 
Soil: Loose, airy mix with bark, coir, and perlite for drainage and moisture retention
 
Repotting: Only when rhizomes reach edge of the pot — typically every 1–2 years
 
Fertilising: Use a diluted, balanced fertiliser every 4–6 weeks in active growth
 
Propagation: Through rhizome division or leaf cuttings with petiole base
 
Hydroponics: Not suitable — needs oxygen and airflow around rhizomes
 
Pruning: Remove faded or damaged leaves to keep growth compact and healthy


Problems you might run into and what to do


 
Leaf browning: Usually due to low humidity or harsh sun — adjust placement
 
Wilting foliage: May indicate overwatering or root rot — check soil and drainage
 
Fungus gnats: Let top layer dry out and use sticky traps as needed
 
Powdery mildew: Improve airflow and avoid overhead watering
 
Mealybugs: Spot treat early with neem oil and isolate if needed


Extra care considerations for long-term success


Begonia U577 prefers stable conditions and dislikes being moved too often. Avoid touching the leaves when wet, and let the rhizomes spread naturally in shallow, wide pots. Its dark coloration stays most vivid in high humidity and low-stress environments. Mimicking its forest-floor heritage — low light, steady warmth, soft airflow — will keep this Begonia compact, lush, and healthy over time.


Etymology and collector context


The genus Begonia was named after Michel Bégon, a 17th-century patron of botany, by French botanist Charles Plumier. The code "U577" refers to its collector or nursery identification, often used for unregistered or unidentified hybrids. These numbers help keep rare types in circulation until formally classified.
