Are you looking for the absolute highlight for your plant collection? Here it is. The titan arum is a botanical sensation and the pride of every botanical garden. Now you have the rare opportunity to raise this wonder of nature from a tiny plant in your own home.

Growth & Appearance (Don't panic about the size!) The titan arum is known for having the largest inflorescence in the world. This can sometimes measure over 3 meters. The plant itself is also a true giant: the tree-like, single leaf that the plant develops in its vegetative phase can reach a height of up to 5 meters! But don't worry: it takes years for the plant to reach these gigantic proportions.

• Growth cycle: The plant always forms only this one leaf from its corm, which looks like a small palm tree. It photosynthesizes for months, then dies back, and the corm enters a dormant phase.

• Slowly growing in size: With each new leaf cycle, the plant and corm get a little bigger. Speaking of corms: this also breaks records and can weigh over 75 kg (in exceptional cases well over 100 kg) when fully grown! However, as a seedling and young plant, it remains absolutely suitable for indoor use for years and grows relaxed in its pot before it (in the distant future) unfolds its full potential.

Location, Care & my personal expert tips This rare plant has precise ideas about its home. To prevent fluctuating temperatures, wind, and unwanted sunlight, pure indoor cultivation is absolutely preferable!

• The right substrate: A purely mineral substrate is recommended. Especially with higher-quality corms like this one, proper care can relatively minimize the risk of rot.

• Watering & Fertilizing: The substrate should be kept constantly moist (but without standing water). I fertilize them with half the dose of "Wuxal" with every watering.

• Lighting: The plants need sufficient lighting during their growth phase. Plant lights are recommended to prevent etiolation.

• Temperature is key: The titan arum loves tropical conditions! The optimal temperature is approx. 25–28 °C. It should be at least 20 °C year-round. It is important to protect the pot from any cold rising from below (styrofoam, heating mat, etc.) The iron rule is: the cooler it is kept, the higher the risk of fatal corm rot.

• The resting phase: When the leaf dies back (usually after approx. 12-24 months), the plant retreats into the corm to rest. Important: Even dormant corms must never dry out completely! The substrate must always remain slightly moist even then.

Origin & Species Protection This exotic plant comes from the warm, humid, shady rainforests of the Indonesian island of Sumatra. There it grows in the undergrowth on steep, well-drained slopes. Since natural habitats are severely threatened, this plant is absolutely protected:

Important note about my plants: The removal of seeds or corms from the wild is strictly prohibited! I am all the more pleased to be able to offer this rarity completely legally and ethically harmlessly: The seeds for growing these seedlings come from a responsible harvest by a specialized nursery directly in Indonesia. By purchasing, you therefore protect wild populations and at the same time contribute to the preservation of this fascinating species.

Special features & ingredients Like many Araceae (Araceae), the plant contains calcium oxalate crystals in all parts and is poisonous. The plant sap can be irritating upon skin contact.

Use The titan arum is a pure, spectacular collector's item. It is the undisputed queen for experienced plant enthusiasts and collectors of rare aroids.

Historical & Curious facts It was discovered in 1878 by the Italian botanist Odoardo Beccari. When a botanical garden announces the blooming of a titan arum, people queue for hours. The reason (besides the insane size) is the smell: to attract carrion beetles and sweat bees for pollination in its homeland, the gigantic flower smells intensely of rotting flesh for about two days. An unforgettable (and fortunately very rare) natural spectacle!
