What Makes Begonia ‘Black Coffee’ So Striking?

This begonia turns heads with its nearly black foliage and luxurious texture.

Here’s what makes it unforgettable:

• Leaf Color: Deep espresso to jet-black leaves with soft metallic undertones; sometimes flecked with hints of burgundy or plum.

• Texture: Thick, velvety leaves with a gentle shimmer in the light.

• Shape: Broad and slightly cupped with subtle ruffling and strong central veining.

• Growth Habit: Compact, upright to slightly mounded, typically 10–14 inches tall and wide.

It’s dramatic without being loud—moody, mysterious, and wonderfully stylish.

Light: Bright Indirect Light Enhances the Color

To maintain its bold black tones, give ‘Black Coffee’ bright, indirect light.

• Indoors: Place it near an east- or north-facing window. For south or west exposures, use sheer curtains.

• Outdoors: Grows well in full shade or spots with soft, filtered morning sun.

Too much direct sun can scorch the leaves or fade their deep color. Not enough light, and the plant may become leggy or dull.

---

Watering: Balanced and Consistent

Like most Rex begonias, ‘Black Coffee’ prefers even moisture—never too dry or soggy.

Here’s your routine:

• Water when the top inch of soil feels dry.

• Use a pot with drainage holes to prevent root rot.

• Avoid overhead watering—wet leaves can develop spots or mildew.

Crispy edges usually mean it’s too dry; mushy stems are a sign of overwatering.

---

Humidity: High Humidity Keeps It Thriving

This begonia prefers 50–60% humidity or higher to keep leaves lush and prevent browning.

To boost humidity:

• Run a humidifier nearby.

• Use a pebble tray with water beneath the pot (but not touching the base).

• Group with other moisture-loving plants.

• Grow it in a glass cabinet or terrarium for ideal conditions.

Dry air can cause crispy leaf edges—moist air keeps the black velvet glowing.

---

Soil: Light, Airy, and Fast-Draining

The roots need air and moisture without sitting in soggy soil.

Use this mix:

• 1 part coco coir or peat moss

• 1 part perlite or pumice

• 1 part high-quality potting soil

You can also use a begonia or African violet mix, which balances airflow and moisture perfectly.

---

Feeding: Monthly in the Growing Season

Feed in spring and summer with a balanced liquid fertilizer, diluted to half strength.

• Do not feed in fall and winter, when the plant is resting.

• Avoid overfeeding, which can lead to salt buildup or leaf burn.

Proper feeding helps it maintain rich color and steady growth.

---

Temperature: Warm and Steady

‘Black Coffee’ prefers temperatures between 60–75°F.

• Protect from sudden drops, drafts, or heat blasts.

• Never let it dip below 55°F—cold can damage the leaves quickly.

• If grown outdoors, bring it inside well before fall chills begin.

Warm, consistent air keeps this begonia happy and healthy.

---

Grooming and Maintenance

A little care goes a long way:

• Remove old or damaged leaves to keep airflow moving.

• Wipe leaves gently with a soft cloth to highlight the velvety texture.

• Pinch back leggy stems to encourage bushier growth.

With routine attention, it stays tidy, lush, and gorgeous.

Propagation: Multiply the Midnight Magic

You can easily propagate ‘Black Coffee’ using leaf cuttings or rhizome division.

Leaf method:

1. Take a healthy, mature leaf with a short stem.

2. Insert the stem into moist soil, or lay the leaf flat with vein cuts.

3. Cover with a clear dome or plastic bag to hold humidity.

4. Keep in bright, indirect light and mist occasionally.

5. Baby plants should appear within a few weeks.

Great for gifting or expanding your dramatic begonia collection.

Common Issues to Watch For

‘Black Coffee’ is generally easygoing, but stay alert to:

• Powdery mildew – Prevent with good airflow and dry leaves.

• Spider mites or mealybugs – Treat early with neem oil or insecticidal soap.

• Root rot – Avoid overwatering and use breathable soil.

Routine checks and a steady environment prevent most problems before they begin.

Styling Tips: Make a Statement with Shadow and Shine
