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.

Amorphophallus barbatus (free reward for donation)

Amorphophallus barbatus (free reward for donation)

50 (80)cm, Amorphophallus barbatus was discovered by late Alan Galloway and described in 2015. It is an extremely rare species which is known from a single location only in central Laos. So far less than a dozen plants have been observed in habitat on the occasion of three excursions over the past ten years. Tubers are from in-vitro propagated material from the original stock on which the description was based on. They have been grown in the soil for one, respectively two growing seasons. Sizes range from ca. 1 cm ø to ca. 3 cm ø (measured at their broadest point). The latter may need one more growing season to reach flowering size.

Tubers from Amorphophallus barbatus will be distributed as free rewards for a donation to cover costs for research studies on the genus Amorphophallus in habitat, for publishing undescribed species, and for maintaining a part of late Dr. Alan Galloway's live Amorphophallus and Typhonium collection which was transferred to us in late 2020.

There are three donation levels:
Level 1: donation of € 120,00 / reward one ca. 1 cm ø tuber
Level 2: donation of € 150,00 / reward one ca. 2 cm ø tuber
Level 3: donation of € 175,00 / reward one ca. 3 cm ø tuber

Shipping is free via signed for/registered airmail from Germany. Shipping is strictly within the EU only.

Tubers will be assigned to donators on a first-come first-served basis. Once no tubers are available anymore at a particular donation level, this level will be stopped. As of 01 July 2021 all tubers have been assignated.

Amorphophallus bulbifer

Amorphophallus bulbifer

100 (150)cm, a medium tall species with a beautiful, showy orange-rose spathe of some 20cm in height and a nicely mottled leaf stalk. Its' leaflets are slightly undulated and have bright-pink margins in a sunny spot. Easily grown in any humus rich, well drained soil. Store dormant corms from late autumn to end of spring in a dry and cool place during winter. This species forms axillary bulbils, which serve for propagation. Additionally, Amorphophallus bulbifer is one out of few species which may be apomictic, i.e. it may set viable seed without prior pollination. Our seeds are high quality seeds from plants cultivated under optimal conditions in Europe. What you will usually find on some some well-known selling platform are imported, low quality seeds stored under mostly inadequate conditions. VII-VIII.
