Seguridad

People

The plant contains calcium oxalate crystals which cause significant irritation to the mouth, tongue, and throat if ingested.

Pets

Begonias are toxic to cats and dogs if ingested, as they contain soluble calcium oxalates.

Children

Keep this plant out of reach of small children and pets, as the leaves and stems are toxic if chewed or swallowed.

Contact allergens

The sap can cause mild skin irritation or dermatitis in sensitive individuals.

Airborne allergens

Begonias are generally not considered significant contributors to airborne allergies.

Edibility

While some begonias are technically edible, they contain soluble oxalates that can cause mouth irritation and kidney issues if consumed in quantity.

Overwintering

Bring outdoor begonias inside before the first frost. Reduce watering during the winter months as the plant enters a period of slower growth.

In containers

Begonias grow very well in containers, provided the pot has excellent drainage and is at least 6 inches wide.

Group plants with similar water needs together to make maintenance easier.

Buenas compañeras

• Impatiens — These plants thrive in the same low light conditions as begonias.
• Coleus — Their colorful foliage provides a nice contrast to the textures of begonia leaves.

Lo que más preguntan

Why are my begonia leaves turning brown?

This is often caused by low humidity or inconsistent watering.

Do begonias need full sun?

Most prefer bright, indirect light, as direct sun can scorch their delicate leaves.

De dónde viene el nombre

The genus was named by Charles Plumier to honor Michel Bégon. The name has remained a staple in horticulture since the 1700s.

Bueno saberlo

• There are over 2,000 species of begonias found in tropical and subtropical regions.
• Begonia flowers are unisexual, meaning individual flowers are either male or female on the same plant.
• They are famous for their asymmetrical leaf shapes, which help them capture light in dense forest floors.
