Amorphophallus (Titan Arum)

Our Amorphophallus collection is the largest in Europe, worldwide it is number two on a private and institutional level (i.e. including botanical gardens). It covers more than 150 Amorphophallus species in more than 500 clones. That means we cultivate three different genetic clones per species on average, in more than 550 pots and a couple of species grown in raised beds.

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. 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. 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 230 different species are known and several new discoveries are made each year. Most species are rarely offered in the trade and thus high-priced botanical gems.
