When the Black Bat Lily decides to bloom

Every so often a plant blooms and the whole greenhouse seems to slow down.

That is what happened this week with the Black Bat Lily, Tacca chantrieri. We have grown Taccas for years, but when the black ones open properly, it still feels special. The flowers are dark and quiet, almost unreal up close. They do not shout for attention. They make you lean in.

Right now, we have a lot of them blooming at the same time. If you have never seen one in person, photos only get you part of the way there. The wings are darker than you expect, and the whiskers seem to go on forever. People walk into the greenhouse, stop, stare, and usually ask the same question: "Is that real?" - Yes. It is.

A quick honest note, because this matters. The blooms themselves are delicate and may not travel well. That is just the nature of this plant. The plants, however, are strong, well established. With the right conditions, they bloom again. This is not a one-time trick.

Black Tacca is not a beginner houseplant, but it is also not impossible. It likes filtered light, steady warmth, and humidity. It does especially well in a greenhouse or a bright indoor spot where you already keep plants that enjoy moisture. It is the kind of plant you keep close, not one you forget in the corner.

We are offering them now simply because they are ready and looking their best. If you have been waiting for one, this is a good moment.

Just wanted to share something we are enjoying in the greenhouse right now. Some plants come and go. Some stay with you.

Tacca (Bat Lily) FAQ

What is Tacca?

Tacca, also known as Bat Lily or Devil Flower, is a tropical plant grown for its unusual bat-shaped flowers with long whisker-like filaments. The most popular species is Tacca chantrieri, the Black Bat Lily.

Is Tacca hard to grow?

Tacca is not a beginner plant, but it is not impossible. It does best with warmth, humidity, and filtered light. Gardeners who already grow orchids, calatheas, or other humidity-loving plants usually do well with Tacca.

Does Tacca need a greenhouse?

A greenhouse is ideal, but not required. Tacca can be grown indoors in a bright spot with indirect light and good humidity, such as near a humidifier or in a bright bathroom with a window or skylight.

Will my Tacca arrive in bloom?

Plants may be blooming in the greenhouse, but flowers are often removed before shipping because they are delicate and do not travel well. The plants are well established and capable of blooming again with proper care.

How often does Tacca bloom?

Tacca does not bloom constantly. It may take time to establish before flowering, but once settled, it can bloom seasonally and may produce multiple flowers in warm, humid conditions.

Does Tacca grow from a bulb?

Tacca grows from a rhizome, not a bulb. The rhizome stores energy and allows the plant to regrow and bloom again.

Why does Tacca have long whiskers?

The long filaments are thought to help attract pollinators such as flies by mimicking the look of decaying organic matter. While unusual, this is part of the plant's natural pollination strategy.

How to Care for Bat Lilies

by Top Tropicals Plant Expert Tatiana Anderson

🌞 Light

• Bright, filtered light. Morning sun or dappled shade is perfect.
• Avoid direct midday sun outdoors — it can scorch the leaves.
• Indoors, place near a bright window with sheer curtains or use a grow light.

🌡️ Temperature

• Warm and stable, ideally 70-85 F during the day.
• Protect from cold drafts or sudden chills.
• Ideally, do not let temperature drop below 45 F, although Taccas can tolerate short period of upper 30's.

💧 Watering

• Keep soil evenly moist but not soggy.
• Water when the top inch feels barely dry.
• Use lukewarm water.
• Avoid letting the pot sit in water.

💨 Humidity

• High humidity (60-80%) is key.
• Mist leaves often, use a humidity tray, or keep near a humidifier.
• In greenhouses or bathrooms with a skylight, it thrives naturally.

🌱 Soil

• Use rich, loose, well-draining mix
• Combine bark, peat, and perlite for ideal airflow around the roots.
• Best mix for growing tropical Tacca in pots - soilless potting mix Abundance . It provides perfect drainage and has a texture similar to a jungle rainforest media.

🍽️ Feeding

• During growth season (Spring through Fall), feed with Green Magic controlled release fertilizer every 6 months. For even better results, you may apply liquid fertilizer Sunshine Boosters Rubusta.
• Stop feeding dry fertilizer in cooler months when growth slows. Liquid Sunshine Boosters are safe to use with every watering, year around.

🏡 Indoor Growing

• Great for bright bathrooms, sunrooms, or any warm, humid corner.
• Rotate pot occasionally for even growth.
• Keep away from heating vents and AC drafts.

🌴 Outdoor Growing (in warm climates)

• Partial shade or filtered light under trees.
• Excellent in large containers that can be brought inside for winter.
• Shelter from heavy rain and wind.
