Gets a medium amount of light, but grows like it wants more. Water every day, but medium is a loose and well draining mixture. It's in a 1 gallon pot and flowers each year. It also goes dormant occasionally, though not necessarily following the seasons. It puts off a ton of really tiny tubers, which do sprout when separated from the main plant - kind of like Dracontium. --Albert +More ---------- Original Message ---------------------------------- Reply-To: aroid-l@lists.ncsu.edu Date: Sat, 28 Jun 2003 23:05:05 EDT >Hello Aroiders, > Can anyone give me any tips on the cultivation of Pycnospatha arietina? >I would appreciate any information on this plant. > >Thanks so much in advance, > >Nancy >FL Zone 10 > ________________________________________________________________ Sent via the EV1 webmail system at mail.ev1.net

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2003.06.29 at 06:43:11(10362) Pycnospatha is a real easy grower and multiplies well if you have it established. An average potting soil is o.k.. If you start out with a rootless tuber, wait untill you see some activity of the apical bud, then pot and water gently. When in leaf keep moist in an average way, nothing special. When the plant dies down, you may want to check the tuber for bad spots but put it back in soil after that. Many thicker roots will remain and they should not dry out. Check regularly for regrowth of the apical bud. In case the plant flowers, that may happen before leafing out or simultaneous with it or after it. When it flowers without leaf, just keep on watering (average) when the flower withers. The leaf will emerge. When you take out the resting tuber, try to avoid the offset-tuberettes to dislodge (they are mostly at the top of the tuber as in Dracontium). Take them off when you replant the main tuber and pot them separately. Most of them will develop new plants.

From: "Julius Boos" ju-bo at msn.com> on 2003.06.29 at 20:37:37(10363) Dear Nancy, Grow in well-drained rich tropical sterile (it is hurt by nematodes!!) mix, plant tuber about 2" deep, grow during the summer months from late to mid-spring till late fall if you can provide the heat it will need, grow hot, 80 degs F. plus, let dry out in fall, it will go dormant, keep soil dry or barely moist in a WARM place in winter, re-pot w/ new soil and begin a LITTLE water in late spring, water more and fert when leaf begins to show, keep soil moist but not water-logged during the growth period. Where did you obtain the tuber? Good luck! Julius +More >>Hello Aroiders, Can anyone give me any tips on the cultivation of Pycnospatha arietina? I would appreciate any information on this plant.

There appear to be two habitat types. In SE Thailand P. arietina occurs in either permanently damp and humid evergreen forest while in central E Thailand it is most often in seasonally dry grassland/woodland margins. Peter

From: "Chanrit Sinhabaedya" siamanthus at hotmail.com> on 2003.06.30 at 14:09:15(10365) Dear Nancy, Pycnospatha arietina are found in East Thailand where it rains in early May to late September. I have seen them growing in the wild in varied conditions. They grow in shady areas to areas much exposed to the sun. They can be found in various types of soils like sandy-clay to loam and humus rich. When growing them, they would flourish in well drained and humus rich soils. They are very easy to grow and would flower well even in low-nutrition soil. You will find that even a tubercle thrown into the ground would grow well. :) Chanrit Sinhabaedya +More Bangkok, Thailand.

Hmmm...I wonder which type I have!!! :) +More Thanks so much again!

From: "Peter C Boyce" levieux.jardin at wanadoo.fr> on 2003.07.02 at 06:29:47(10372) Hi Nancy In the wild plants from the monsoonal east are smaller in all their vegetative dimensions and the leaf divisions are finer and, well, more divided. The largest plants I have seen from th east are a shade under 1.5 metres tall in mature leaf. Plants from the per-humid south are very robust - I have seen them with leaves to 3 metres tall with a blade 1.5 metres in diameter. I known that Wilbert has plants from the south and I am pretty sure that he also has plants from the east, perhaps he could comment whether these size and leaf division observations from the wild remain stable, or not, in cultivation.

From: "Julius Boos" ju-bo at msn.com> on 2003.07.04 at 13:36:59(10374) Dear Pete, I thought (I was mistaken!) that Nancy was asking about the second species of Pycnospatha, (P. palmata from the North, discussed in Bogner (1993c) )?), but I am not certain if this is still a 'good' species. I was not aware that there was this variation in the two populations of P. arietina you mention, interesting stuff! Hopefully Wilber will enlighten us somewhat further!

From: "Julius Boos" ju-bo at msn.com> on 2003.07.06 at 16:15:23(10377) Hi Julius<< Hello Pete, Yes, I felt certain that P. palmata was a 'good' species, the two populations of P. arietina that differ one from the other for a moment had me a little confused!. Many years ago Josef sent me a copy of his 1973 paper reviewing this genus, and from this paper I obtained the collection data on P. palmata. I gave this information to friends who were traveling and collecting in those areas, and lo and behold they managed to collect substantial quantities of this rare species! I believe that most if not all the plants now in cultivation in the U.S.A. are from that one collection. This genus seems very prone to nematode damage, so all of you out there growing it take care! It is indeed a shame that Josef is not 'on' e-mail, he is a wealth of invaluable information. Thanks again, The Best, Julius +More Pycnospatha palmata is still a good species, and most distinct from P. arietina. For a long time after it's discovery in Lao PDR in the 19th Century P. palmata was known only from the original herbarium specimens in Paris. However, it was rediscovered in Thailand in the 1990s. It is a much smaller plant with leaves not unlike Tacca palmata and a cute inflorescence a fraction the size of that of P. arietina. It is also easy growing although plants at Kew seemed to do best given a reasonably 'hard' rest; not surprising, I guess, given their monsoonal provenance. It's a great pity that Josef eschews email and isn't a member of aroid-l since he could give some great insights into Pycnospatha. As ever Pete
