Begonia blancii – Compact Tropical with Mottled Foliage

Begonia blancii is a rare species from the island of Palawan in the Philippines, prized for its textured, semi-succulent leaves and creeping growth habit. Its foliage is round to ovate, often displaying a rich green tone with subtle or striking mottling depending on the form. With its low-growing, horizontal spread and soft stems, it makes a great fit for terrariums or shallow planters. Unlike many upright Begonias, this one creeps outward from a rhizome, making it a lush ground-level feature plant.

Problems You Might Encounter
 
Yellowing Leaves: Usually linked to overwatering or poor drainage; adjust soil and watering frequency
 
Crisping Edges: Caused by dry air or underwatering; raise humidity and check soil moisture
 
Pests: Can attract mealybugs or spider mites in dry environments; treat early with neem or insecticidal soap
Further Notes on Growing
Begonia blancii adapts well to indoor environments if humidity is high and airflow is balanced. Terrarium growers value it for its compact size and ability to root along creeping stems. Replicating its warm, moisture-rich habitat leads to robust growth and better resistance to stress. It’s a fantastic choice for small spaces, especially when displayed against a darker background to highlight its leaf texture.
Name Origins and Description
Begonia blancii was formally described in 2011 and named in honor of French botanist Patrick Blanc. It belongs to the large and morphologically diverse Begoniaceae family.
