What is a Begonia Black Knight?
The Begonia Black Knight is a cultivar of the Rex Begonia, known for its large, textured leaves. This particular variety boasts deep burgundy foliage with an almost iridescent quality. A ring of pink and white speckles outlines the dramatic leaf shape, adding a whimsical touch.
How do I care for a Begonia Black Knight?
Here’s the thing: The Begonia Black Knight isn’t the easiest plant. It thrives in bright, indirect light – think dappled sunlight filtering through a sheer curtain. Direct sun will scorch the leaves.
Watering is key. Aim for moist but not soggy soil. Let the top inch dry out before watering again. Avoid wetting the leaves directly, as this can promote fungal diseases. Opt for bottom watering, where you place the pot in a shallow dish of water and let it soak up the moisture.
Humidity is another crucial factor. Rex Begonias love a humid environment. You can group your Begonia Black Knight with other humidity-loving plants, use a pebble tray filled with water, or invest in a humidifier.
What kind of soil does a Begonia Black Knight need?
A well-draining, loose potting mix is ideal. Look for a mix specifically formulated for African Violets or Begonias. You can also create your own by combining potting soil, perlite, and orchid bark for optimal drainage and aeration.
Does the Begonia Black Knight flower?
The Begonia Black Knight is primarily grown for its foliage, and the flowers are rather insignificant. They’re small, pink, and inconspicuous compared to the showstopping leaves. You can pinch off the flowers to encourage more leaf growth.
How big does a Begonia Black Knight get?
Mature Begonia Black Knights can reach a height and width of around 12-18 inches. The leaves themselves can grow up to 6 inches long and wide.
Is the Begonia Black Knight poisonous?
Unfortunately, yes. The Begonia Black Knight, like most Begonias, is mildly toxic. It contains calcium oxalate crystals, which can cause irritation in the mouth, stomach, and skin if ingested. Keep this in mind if you have pets or small children.
How do I propagate a Begonia Black Knight?
Propagating a Begonia Black Knight is relatively straightforward. You can take leaf cuttings or stem cuttings. For leaf cuttings, choose a healthy leaf and cut it off near the base of the petiole (leaf stalk). Plant the petiole in a moist potting mix and keep it warm and humid. For stem cuttings, take a section with a few nodes (where leaves grow) and follow the same procedure.
What are some common problems with Begonia Black Knight?
Here are a few things to watch out for:
- Brown, crispy leaves: This can be caused by underwatering, low humidity, or excessive sunlight.
- Yellowing leaves: Overwatering is the most likely culprit.
- Fungal diseases: Fungal diseases can occur if the leaves are constantly wet or there’s poor air circulation.
- Pests: Mealybugs and spider mites are common pests on Begonias. Treat them with insecticidal soap or neem oil.
Can I grow a Begonia Black Knight outdoors?
Technically, yes, but only in areas with consistently warm temperatures and high humidity. In most climates, it’s best to keep your Begonia Black Knight happy indoors.
What are some good companion plants for a Begonia Black Knight?
Here are some plants that share similar care requirements:
- Prayer Plant (Maranta leuconeura): Another humidity-loving beauty with stunning foliage.

Begonia Black Knight vs. Begonia Tiger Paws:
Both are Rex Begonias with dramatic foliage. The Black Knight boasts deep burgundy leaves with speckles, while the Tiger Paws has green leaves with dark red, almost velvety markings that resemble paw prints. The Tiger Paws is generally considered slightly easier to care for.
Begonia Black Knight vs. Caladium:
Both have beautiful, patterned leaves. The Black Knight’s leaves are a solid color with speckles, while Caladiums come in a wider variety of colors and patterns, often featuring contrasting veins or a combination of green, pink, white, and red. Caladiums also tend to go dormant in winter, losing their leaves, while the Begonia Black Knight is evergreen with proper care.
