Amorphophallus (Titan Arum) & Pseudodracontium

Titan Arums and the closely related genus Pseudodracontium include several species with some of the largest inflorescences within the floral kingdom. They usually develop only a single, large leaf on a stout stem, resembling almost a tree-trunk. All make one long rhizomatous or a round corm (a "bulb"), 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 and easily cultivated. They will thrive in any humus rich, well drained substrate (with up to 70% peat 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 10°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, i.e. they will not increase in size anymore.
All plants are available in small quantities only and the rarer ones will usually sell out within few days !

Amorphophallus albus (Yellow Yunnan Titan Arum)

Amorphophallus albus (Yellow Yunnan Titan Arum)

100cm, Yellow Yunnan Titan Arum from China growing at up to 2.000m. Has a creamy green to yellowish spathe and yellowish spadix on a 20cm to 30cm stem. Hardy in the garden in warmer regions in Central Europe, provided that corms are planted rather deep with soem excellent drainage and some additional protective dry mulch layer, so that the soil will never fall wet nor freeze through in winter. Alternatively store corms in a dry and cool place during winter and plant out again by the end of spring. Very easy in any humus rich, well drained soil. 5cm to 10cm ø corms are flowering size. USDA climate Zone 9. VI-VII.

Dormant plants (i.e. tubers or corms) are available in our shop from October through May.

Note: All corms are available for a delivery within Europe only ! Seeds are shipped worldwide.

Native of rich, well drained soils in woods in North Central Thailand (Sara Buri). This species makes elongated, vertical rhizomatous corms, the size is given as length.

Amorphophallus bulbifer

Amorphophallus bulbifer

100 (150)cm, one of the smaller and handier species with large orange rose colored spathe of some 40cm in height and a speckled stem. Its' leaflets are slightly undulated and have bright-pink margins in a sunny spot. Very easy in any humus rich, well drained soil. The corm endures slight frost in autumn if it is planted rather deep (up to some 20cm/8") and sheltered from excessive moisture. The leaf will die back with first freezing as it is not sufficiently winter hardy for a permanent open garden cultivation in Central Europe and N USA. Store corms from late autumn to end of spring in a dry and cool place during winter. Makes some bulbils in leaf axils, which may serve for vegetative propagation. 8cm to 12cm ø tubers are flowering size. VII-VIII.

Amorphophallus konjac (Konjac Titan Arum)

Amorphophallus konjac (Konjac Titan Arum)

150 (200)cm, Konjac Titan Arum is probably the easiest and one of the showiest species in this genus. It has an impressive dark purple red spathe of 40cm in height. For a sunny or partially shaded spot, in summer this robust species may be even grown in the open ground in the garden in Central Europe if corms are planted rather deep with an extra shelter from winter wetness and freezing through (e.g. thick dry mulch layer). 8cm to 16cm ø tubers are flowering size. USDA climate zone 9/10. IV-VI.
