Amorphophallus (Titan Arum) & Taccarum

We are proud to host the broadest private Amorphophallus collection throughout Europe and the second largest private collection worldwide with more than 140 different species in our cultivation at present! We grow more than 500 different clones, i.e. more than three different genetic clones per species on average, in more than 550 pots.

Titan Arums include several species with some of the largest flowers within the floral kingdom. They usually develop only a single, large leaf on a stout stem, which may resemble a tree-trunk in giant species. Taccarum species from South America have an overall similar habit, yet they usually develop several leaves per plant in one growing season and the inflorescence differs from those of Amorphophallus. All make a long rhizomatous or a round corm (a "tuber"), weighing up to 60kg in their largest member, namely Amorphophallus titanum from Sumatra. The offered subtropical species remain a little bit more manageable for their overall smaller size. They will thrive in any humus rich, well drained substrate (with up to 70% peat or any other humus rich substrate added). As soon as they start to grow (usually in spring) they require sufficient warmth with a minimum of some 20°C and a semi-moist soil in a partially shaded spot. As soon as the leaf starts to yellow (which is usually in autumn), keep plants rather dry at a minimum of some 15°C. Store corms in a warmer spot with beginning of spring the following year and carefully restart to water as soon as the new leaf appears from the center of the corm. With maturity plants may form an inflorescence instead of a leaf. After flowering most specimens will usually form a new leaf in the same year. Please note that plants marked as "flowering size" in the shop do not necessarily flower the year of potting, but are mature plants for their weight. For their decorative foliage, unique growth habit and outstanding inflorescences all Amorphophallus species are perfect collector's items, however only some 10 species are more widely available. At present more than 210 different species are known and several new discoveries are made each year. Most species are exremely rarely offered in the trade and thus high-priced botanical gems. Plants (i.e. dormant corms) are usually available between September and May.

All offered tubers descend from cultivated plants! We do not offer wild collected tubers and strictly discourage our clients in buying such plants, which may have been exported illegally in some cases. In several aroid species wild populations are decreasing alarmingly due to professional wild collections in habitat. Neither do we sell imported tubers from Asia which might be infected with several serious pests and might have been stored under totally inappropriate conditions. Wild collected as well as imported tubers you may find at various selling platforms at probably lower prices, but these imported plants will never reach the quality of our tubers! If you see a picture of a tuber with some white dustlike cover on it, then it is an imported tuber. In order to receive a plant health certificate for export from local authorities in India and Thailand, tubers have to dusted with some white fungicide.

At present we are propagating a very good selection of tuber-forming aroid species within the following genera: Amorphophallus, Anchomanes, Ariopsis, Arisaema, Arum, Biarum, Colletogyne, Dracontium, Dracunculus, Gorgonidium, Helicodiceros, Pinellia, Pseudohydrosme, Spathantheum, Taccarum, and Typhonium. A full list of what may become available next autumn is available on this page: "Amorphophallus, Arisaema, Arum, Dracontium and Typhonium in propagation". We do not propagate these species at large scales and from the rarer aroids very few tubers will be available. Please note, that we do not take backorders nor reservations. Thus please bookmark this page and come back to us in the course of late summer and autumn to check availability of tubers and seeds.

Price is given per package (3 seeds) or per dormant corm (diameter given in ø cm or length given in cm).

Note: All corms are available for a delivery within Europe only ! Seeds are shipped worldwide. For Non-European customers only: We do ship dormant tubers outside Europe, provided that all risk is upon the buyer. We do not issue any phytosanitary certificate, which is officially required for most countries. We kindly ask you to check with your local import regulations before placing an order!
