Arisaema (Cobra Lilies)

Dragon Plants or Cobra Lilies have their main distribution in Asia (China), only few species occur in North America. They are aroids which are rather new to public cultivation and only about ten (out of some 200) are sometimes available at specialized nurseries. All Arisaema species offered on this page will be successfully grown in the open garden where they receive enough moisture in summer and are sheltered from moisture in winter. They are summer green and winter dormant. Plant depth of the tubers or corms is three times their size.
Sow seeds in any rich peaty, well drained soil at some 10°C - 20°C, higher temperatures will inhibit germination in most Arisaema species. Germination is irregular and might start well after only some 2 weeks or may need up to 3 months and more. If seeds from species from cool temperature climates will not have not germinated after three months, keep pots outside in a protected spot during winter. Seeds will then germinate by the end of following spring. Keep seedlings in their pots for at least two years in a partially shaded spot. Stop watering by mid September or as soon as leaves start to yellow. In cold regions it is recommendable to unpot dormant young tubers and to store them dry in the fridge at some 5°C to 7°C during winter. For tropical species please refer to the detailed information given for each species. Repot tubers in early spring.
For detailed information on sowing and cultivation of Cobra Lilies please have a look at this website: "The Genus Arisaema" (www.arisaema.info)
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 import plants will never reach the quality of our tubers!
All are USDA Climate Zone 7 unless otherwise specified.
Price is given per package (10 seeds) or per dormant corm (size in ø cm).
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. 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!

Arisaema sikokianum (Shikoko Cobra Lily)

Arisaema sikokianum (Shikoko Cobra Lily)

40 (60)cm, Shikoko Cobra Lily is among the most elegant Arisaema species with a dark brown spathe and white spadix with a very broad tip. It is native of humus rich soils in sunny spots in woods in Japan. It is rarely cultivated and propagation is mainly by seed as it usually does not make any (or only few) offsets. For any humus rich, very well drained soil with some excellent winter protection. In colder regions preferably grow in pots under frostfree conditions in a sunny spot throughout the year. During dormancy in winter keep plants almost completely dry at some 10°C. USDA Climate Zone 8/9. IV-V.

Note: In the commercial trade wrongly labelled plants are commonly distributed under the names "Arisaema sikokianum" ex China, "Arisaema sikokianum var. serratum", or "Arisaema sikokianum var. henryianum". All these are imported plants from a single source in China (namely Chen Yi Nursery) and neither represent any type nor form of the real Arisaema sikokianum (endemic to Japan), but are either Arisaema engleri or Arisaema serratum ! If you do not want to be disappointed and to lose a lot of money for the usually high-priced Arisaema sikokianum, we recommend to avoid buying any plants with the above mentioned names and to make sure that plants are not of Chinese origin.
