How to Propagate Amorphophallus titanum from Seeds – The Queen of Rare Plants at TOMs FLOWer CLUB

The Amorphophallus titanum – also known as the Titan Arum or Corpse Flower – is one of the rarest and most fascinating plants on earth. Famous for producing the largest unbranched inflorescence in the world (and its legendary scent during bloom), it is also a coveted collector’s treasure for botanical enthusiasts.

At TOMs FLOWer CLUB, we’re passionate about rare and organically grown plants – and we know many of our followers and customers are curious:
How do you actually propagate such a unique giant from seed?

Propagation Through Seeds – A Lesson in Patience and Botanical Art

Propagation of Amorphophallus titanum is possible via corm division or seeds, but seed propagation is the most natural and rewarding – if you're willing to wait!

Here’s what you need to know:

1. Getting Viable Seeds

The seeds of A. titanum are only available after successful hand-pollination, usually between two flowering specimens – one functioning as female and the other as male (as the plant does not produce both functions at once).

Seeds are pea-sized, typically orange-red when ripe, and must be fresh to germinate well. At TOMs FLOWer CLUB, we propagate ethically and never rush nature.

2. Sowing the Seeds

• Substrate: A well-draining but moisture-retaining mix is crucial. We recommend a blend of coco coir, perlite, and fine bark – similar to what we use in our self-mixed organic substrate.

• Moisture: Keep the substrate consistently moist (not wet). Use a humidity dome or clear container.

• Temperature: Ideal is 24–28°C for germination. Warmth and patience are key.

• Light: Bright, indirect light – never direct sun at this stage.

3. What to Expect

Germination can take 4–12 weeks, sometimes longer. The seed will develop a small tuber (corm) first – which is the plant's storage organ. From here, the iconic single umbrella-like leaf will sprout.

Growth is very slow in the first years – but absolutely worth it. Each season the plant will go through a dormancy phase before pushing a new, larger leaf.

4. Caring for Young Plants

At TOMs FLOWer CLUB, we never over-fertilize – and you shouldn’t either. Use organic fertilizer sparingly and allow the plant to follow its natural rhythm, including hibernation from approx. November to March.

Potting is done in clay pots with good drainage, and repotting is only needed every 1–2 years, as with many aroids.
