Begonia ‘Harmony’s Tazmanian Devil’: Wild Foliage with a Spirited Twist
A Complete, Easy-to-Follow Growing and Care Guide for This Bold and Beautiful Rex Begonia
When you're looking for a begonia that breaks all the rules and spins onto the scene with untamed energy, Begonia ‘Harmony’s Tazmanian Devil’ delivers. This stunning Rex begonia is known for its dramatic spiral leaf shape and high-contrast coloration. Just like its namesake, it’s fierce, fast-growing, and full of personality. Whether you're building a begonia collection or simply want a conversation-starting houseplant, this one brings the drama in all the best ways.
What Makes ‘Harmony’s Tazmanian Devil’ So Wildly Wonderful?
This begonia doesn’t tiptoe around—it bursts into your space with color and motion.
Here’s what makes it stand out:
-
Leaf Shape: Strong spiral formation at the base of each leaf—twisted, curled, and powerful.
-
Color Pattern: Vivid silver centers spiraling outward into deep burgundy or nearly black edges, sometimes highlighted with hints of pink or green.
-
Texture: Velvety and richly patterned with high contrast for dramatic effect.
-
Growth Habit: Compact and mounded, usually 8–12 inches tall and wide.
It’s a Rex begonia with attitude—and it makes an unforgettable first impression.
Light: Bright, Indirect Light Keeps It Spiraling Strong
To bring out the contrast and maintain healthy, compact growth, place ‘Tazmanian Devil’ in bright, indirect light.
-
Indoors: East-facing windows are ideal. A south or west window works too with sheer curtains to filter the sun.
-
Outdoors: Only grow in full shade or areas with very gentle, dappled morning sun.
Too much sun can burn or bleach the leaves. Not enough light may cause the spiral shape to stretch out or fade.
Watering: Keep It Steady, Not Soggy
Rex begonias prefer even moisture, but soggy soil can lead to rot quickly.
Follow this watering rhythm:
-
Water when the top inch of soil feels dry.
-
Always use a pot with drainage holes to allow excess water to escape.
-
Avoid splashing water on the leaves to prevent spotting or mildew.
-
Reduce watering during winter when the plant’s growth slows.
Watch for signs: crispy edges mean it’s too dry, and soft, droopy stems mean it may be too wet.
Humidity: Loves a Moist, Warm Environment
This begonia thrives in moderate to high humidity, especially in warm indoor spaces.
Aim for 50–60% humidity or more:
-
Use a humidifier or place on a pebble tray with water.
-
Keep it near other tropical plants to create a moisture-rich zone.
-
It’s a great fit for a plant cabinet or terrarium.
Dry air leads to browning and leaf curl. Consistent humidity keeps it vibrant and full.
Soil: Loose and Breathable Is Best
The roots need room to breathe. Choose a light, well-draining mix.
Perfect blend:
-
1 part coco coir or peat moss
-
1 part perlite or pumice
-
1 part high-quality potting soil
A begonia or African violet mix also works beautifully for these fussy but fabulous roots.
Feeding: Monthly During the Growing Season
Feed ‘Tazmanian Devil’ once a month in spring and summer with a balanced liquid fertilizer diluted to half strength.
-
Avoid feeding in fall and winter—this is rest time for Rex begonias.
-
Overfeeding may cause leaf damage or stretch the tight growth pattern.
Feeding lightly but consistently supports strong leaves and vibrant color.
Temperature: Keep It Warm and Consistent
This begonia thrives in temperatures between 60–75°F.
-
Avoid drafts, heating vents, or cold windowsills.
-
Never let it drop below 55°F.
-
If grown outdoors in warm weather, bring it in well before nighttime temps fall.
Sudden temperature changes can stress the plant and dull the dramatic spiral form.
Grooming and Maintenance
This begonia loves a little attention:
-
Remove dead or damaged leaves to improve airflow and appearance.
-
Wipe leaves gently to remove dust and let the silver tones sparkle.
-
Pinch back lightly if the plant gets leggy—this encourages fuller, bushier growth.
A tidy begonia is a happy begonia, especially when it's as bold as this one.
Propagation: Multiply the Madness
You can easily propagate this variety using leaf cuttings or rhizome division.
Leaf cutting method:
-
Choose a healthy, mature leaf.
-
Cut it with a short petiole or make slits along the main veins.
-
Press into moist soil and cover with a humidity dome or plastic bag.
-
Keep in bright, indirect light and mist occasionally.
-
Baby plants will appear in 2–4 weeks and can be transplanted once rooted.
Great for gifting—or expanding your indoor “wildlife.”
Common Issues to Watch For
Like other Rex begonias, ‘Harmony’s Tazmanian Devil’ can be sensitive. Watch for:
-
Powdery mildew – Caused by high humidity and poor airflow. Space out your plants and avoid overhead watering.
-
Spider mites – Boost humidity and treat early with neem oil or insecticidal soap.
-
Root rot – Caused by overwatering or poor drainage. Always check the soil before watering.
Keep a close eye, and this plant will reward you with continuous growth and flair.
Styling Tips: Let the Devil Dance
With its high drama and intense swirl, this begonia belongs front and center.
Try displaying it:
-
In a dark or metallic pot to play off its bold edges.
-
Solo on a plant stand or pedestal for maximum visual impact.

Alongside other spiraled or spotted begonias like ‘Escargot,’ ‘Harmony’s Twisted Sister,’ or ‘Fireworks.’
