✅ Simple rules that actually make them bloom and grow well

• Light - The more light, the better the growth and flowering. Full sun is ideal, but in very hot climates, filtered bright light keeps plants looking healthier.
• Water - Water well, then let soil dry on the surface. Sitting in wet soil damages roots, but letting plants dry out too often can push them into early dormancy.
• Pot and shaping - Use a shallow pot with excellent drainage. To develop a sculptural caudex, lift the plant slightly each time you repot and remove some of the top soil so upper roots become exposed. Over time, this creates a thicker, more prominent base.
• Soil - Use a fast-draining Adenium potting Mix.



Healthy adeniums start with the right foundation - a fast-draining soil mix and careful watering only when dry to avoid caudex rot.


• Cold hardiness - Adeniums are tropical and do not tolerate frost. Keep above 40 F. Brief drops to mid 30s may be tolerated if dry, but cold and wet conditions can damage or kill the plant. In cooler climates, bring indoors or protect during cold nights.
• Indoor winter care - Move plants indoors before cold nights. Place in the brightest spot possible, ideally a south-facing window. Or use additional lighting. Water very lightly and less often, as growth slows. Do not fertilize during dormancy. Some leaf drop is normal in winter.



Freshly grafted adeniums in dormancy - a crucial resting phase. Keep watering low (once a month) and avoid overcare; this is the time to let them rest and etablish.


• Feeding - Adeniums respond best to liquid fertilizer. We apply Sunshine Megaflor Booster with each watering throughout the year. During dormancy, watering is reduced, so fertilizer use decreases accordingly. Consistent, light feeding promotes strong roots, a thicker caudex, and improved flowering.
• Pruning - For multiple blooms, regular pruning is essential. After flowering, cut back long or leggy growth to stimulate branching. Each new branch can produce more buds, leading to a much fuller bloom in the next cycle.

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.
