Care Guide | Bat Flower Plant
If you think you’ve seen unusual flowers before, the Bat Flower Plant will make you look twice—its dramatic, wing-shaped blooms and long, whisker-like filaments resemble a flying bat in midair. Belonging to the Tacca genus, these exotic plants are prized for their mysterious appearance. There is a Black Bat Plant (Tacca chantrieri) and a White Bat Plant (Tacca integrifolia).
Characteristics
Bat plants are tropical, clump-forming perennials that thrive in warm, humid environments with filtered light. They prefer rich, well-drained soil and consistent moisture. These plants typically grow 2–3 feet tall with large, glossy leaves that create a lush, tropical look. Their most notable feature is their unusual flowers, which include broad “wings” (bracts) and long trailing filaments that can reach over a foot in length. Bat plants are not the easiest to grow, but with the right conditions, they can reward you with truly spectacular blooms.

Scientific Name
The bat plant belongs to the Tacca genus in the Dioscoreaceae family. The most well-known species are Tacca chantrieri, known for its dark, almost black flowers, and Tacca integrifolia, which produces striking white blooms with purple accents.
Classification
Bat plants are herbaceous tropical perennials that grow from rhizomes. They produce large, lance-shaped leaves and some of the most unusual flowers in the plant world. The blooms consist of modified bracts and long, thread-like “whiskers,” giving them their signature bat-like appearance.
Origin
Tacca species are native to the tropical rainforests of Southeast Asia, including countries like Thailand, Malaysia, and southern China. In their natural habitat, they grow beneath the forest canopy, where they receive filtered light, high humidity, and consistently warm temperatures.
USDA Hardiness Zones
Plants have a culture they prefer, just as people from various countries and households have their own customs and traditions. The U.S. Department of Agriculture created the USDA hardiness zone map to help gardeners identify the areas in which plants tend to grow well based on past average temperatures/climates. On the USDA's site, you can enter your zip code to identify your hardiness zone.
Bat plants thrive in Zones 10–11, where temperatures remain warm year-round. They are highly sensitive to cold and should be grown indoors or in controlled environments in cooler regions.
No fear if you live outside the hardiness zone—you can still grow bat plants successfully indoors by mimicking their natural tropical conditions.
Height Potential
Bat plants typically grow to about 2–3 feet tall and wide. Their large leaves can spread outward, giving them a full, lush appearance even when not in bloom.
Planting
Plant bat plants in containers or garden beds with rich, well-draining soil high in organic matter. They are ideal for shaded patios, greenhouses, or indoor spaces with adequate humidity.
When planting in containers, ensure good drainage and use a loose, airy potting mix. Avoid compacted soils that retain too much water.
Light
Bat plants prefer bright, indirect light or partial shade. Direct sunlight can scorch their leaves, while too little light may reduce blooming. A spot near a filtered window or under a shade cloth works well.
Soil/Watering
Keep soil consistently moist but not soggy. Bat plants are sensitive to both drought and overwatering. Use well-draining soil rich in organic matter, and allow only the top layer to slightly dry between waterings.
High humidity is essential—consider misting regularly or using a humidity tray or humidifier.
Fertilizer
Feed bat plants with a diluted, balanced fertilizer every 2–4 weeks during the growing season (spring through early fall). Reduce feeding during winter when growth slows.
Pruning
Minimal pruning is required. Remove yellowing or dead leaves and trim off spent flowers to keep the plant looking tidy and to encourage new growth.
Cold Weather Care
Bat plants are extremely sensitive to cold and should be kept above 55°F (13°C). Avoid drafts, sudden temperature changes, and cold windows. In cooler climates, they must be grown indoors or moved inside during colder months. Learn more in our Overwintering Guide.
Common Pests
Bat plants can be susceptible to spider mites, aphids, and mealybugs, especially in dry indoor conditions. Regularly inspect leaves and treat infestations early with insecticidal soap or neem oil.
Toxic to Pets?
Bat plants are considered mildly toxic if ingested and may cause irritation or digestive upset in pets. It’s best to keep them out of reach of curious animals.
After Arrival Care
Please give your plant a little TLC after its journey through the mail 📬. Here are a few steps we recommend:
- Unwrap immediately to provide fresh air to the plant and soil.
- Wait a few days before exposing to full sunlight so your plant can adjust after being in a dark box for several days.
- Always protect from heat and cold because temperature extremes can be stressful or deadly for plants.
- Water. Your baby plant may be parched and even a little wilted but thorough hydration will help it recover.
- Grow out in a larger pot to increase your chances of success—i.e., a quarter gallon—Then transplant to the ground or the next pot size up once the roots fill to the bottom. This will help the plant get sufficient water and nutrients directly to the roots.
Learn more in our After Arrival Care Guide.
Repotting
We highly recommend growing your baby plant out in a larger pot 🪴 to increase your chances of success
You don’t have to repot immediately, but the sooner you do, the more room it has to grow.
Here are some general repotting tips:
- Start with a pot that's 1-2 inches larger in diameter than the starter-sized pot it came in. A pint or quart would be great.
- Transplant to the next pot size up once the roots fill to the bottom.
