🌸 Adenium Care Basics

Adeniums have many spectacular hybrids, and their basic culture is closer to orchids than to typical houseplants. The key is a small pot, excellent drainage, bright light, and careful watering.

Pot and Soil

  • Use a small pot sized to the root system.
  • Excellent drainage is required.
  • Use a very well-drained mix. We recommend specially formulated for Adeniums Desert Rose Soilless Mix

Light and Blooming

  • Give lots of light for heavy flowering.
  • In warm conditions and longer days, most hybrids and species begin blooming in spring.
  • In warmer climates they can keep blooming through fall and winter.

Watering (Most Important)

  • Adeniums dislike both extremes: over-watering and drying out too often.
  • Use neutral to hard water when possible.
  • Acidic water can sour the mix quickly and may cause root rot.
  • Water in the early morning so the plant can drink through the day.
  • Watering frequency can range from daily to every few days, depending on heat, light, and how fast the mix dries.
  • Never let the pot sit in a saucer of water.
  • Do not let the plant dry out too often, or it may go into early dormancy.
  • Do not wet the leaves.

Fertilizer (Caudex + Flowers)

  • To build a large swollen base/trunk (caudex), use a good quality fertilizer.
  • A fertilizer that helps trunk swelling also supports flowering. The best choice for this is Sunshine Megaflor.
  • Avoid fertilizers that are too high in nitrogen; choose a formula where the middle number is the highest.
  • Never apply fertilizer directly on roots.
  • Do not liquid feed a thirsty plant.
  • Always water lightly first, then feed, to avoid root burn and leaf drop.

The Caudex "Secret" (Shaping the Base)

  • At each repotting, lift the plant slightly so the upper roots are a little exposed.
  • This encourages new roots to grow downward and helps create a thicker, more interesting caudex shape.

Multi-Grafted Plants (Important Note)

  • Adenium hybrids can be multi-grafted with several colors/varieties on the same plant.
  • The swollen base forms only when the rootstock plant is grown from seed.

✍️ Adenium FAQ

How much light do Adeniums need?

Adeniums need lots of light for heavy flowering. Most hybrids and species start blooming when conditions are warm and days get longer, and in warmer climates they can keep blooming through fall and winter.

What is the best pot size for Adeniums?

Use a small pot sized to the root system, with excellent drainage. A small pot with excellent drainage is a must.

What kind of soil mix should I use?

Use only a well-drained mix. Adeniums do best in very well-drained soil. A small pot plus excellent drainage is the foundation of success.

How often should I water Adeniums?

Adeniums do not like both over-watering and drying-out too often. Water preferably in the early morning and do not water again until the mix dries on the surface. Watering can range from daily to every few days depending on heat, light, and how fast the mix dries.

Can Adeniums sit in a saucer of water?

No. Never allow your Adenium to sit in a saucer of water.

Should I wet the leaves when watering?

No. Do not wet the leaves.

What kind of water do Adeniums prefer?

Adeniums prefer neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot.

How do I create a large, swollen caudex?

At each repotting, lift the plant slightly so the upper parts of the roots are a little exposed. This encourages the plant to form more roots that grow downward and helps create a thicker, more interesting caudex.

What fertilizer should I use for caudex growth and blooms?

Use a good quality fertilizer to support both trunk swelling and flowering. Avoid formulas that are too high in nitrogen; the middle number should be the highest. Never apply fertilizer directly on roots, and do not liquid feed when the plant is thirsty. Water lightly first, then feed, to avoid root burn and leaf drop.

Can an Adenium have multiple flower colors on one plant?

Yes. Adenium hybrids can be multi-grafted with several colors or varieties on the same plant. Note that the swollen base forms only when the rootstock plant is grown from seed.

When the Black Bat Lily decides to bloom

Blooming Black Bat Lily (Tacca chantrieri) with dark bat-shaped flower 
and long whisker-like filaments surrounded by green leaves

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.

bat-shaped flowers and long whisker-like filaments in a greenhouse

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.

Smokey: I finally got these Taccas. I wanted them for a long time. I think I got a little attached already. They look like something from a Tim Burton movie. And look at that flower. It even has whiskers like me.
Sunshine: I understand. I get emotionally attached very fast too. Mostly to coffee.
