Dioscorea discolor
Glad I found one tuber at the very bottom of the pot. Sad it didn't multiply. This year I will water and fertilize more.
Btw all three stem cuttings I made last year rooted and made some friends happy. Will dot that again this year.

Tecophilea violiflora

Does someone in EU grow any of the various cultivars of Amorphophallus konjac out there like Leo Song, Shattered Glass, Gordon's Gold, Nightstick etc and has spare tubers either willing to send to me directly or preferably via the EU PBS Exchange (so any PBS member can have a shot at them)?

I think the cutting is too old and it is too far in season to accomplish a successful propagation. I removed one of the two branches and all but two leaves on the remaining branch. But no guts no glory.

My Amorphophallus linearis is still active. I don't want to disturb the plant to see if the tuber I received from the pbs exchange has grown and made new offsets. I found this online description of propagation by leaf cuttings (https://www.juniperlevelbotanicgarden.org/propagation-of-amorphophallus-by-leaf-petiole-cuttings/). However A. linearis is not mentioned. Besides that never done it before on any kind of Amorphophallus. Is it worth to give it a try at this time of year (end of summer). Any other suggestion how to proceed are welcome.

Uli: My Dioscorea discolor plant was the whole time indoors but that was more coincidental than planned. I liked the leaves so much I placed it next to the door to backyard and just forgot to move it outdoors in summer. At first it was staked about 60 cm but since the new shoots are rapidly growing I put in new stakes that are 1.8 m tall. Long term osmocote granulate fertilzer was added to the soil.  And I added 2 weeks ago potassium through the use of dried pulverized banana peel. The top two leaves with each one node of the main shoot are now in a aquaponics propagator. Hopefully they will root.

GC100. There are indeed a lot of shops that shell Dioscorea seeds like D. elephantipes and D. mexicana. Easy to grow but it takes a lifetime to get big tubers. So I'm more interested in fast growing Dioscorea like D. sansibarensis, D.  bulbifera and D. floribunda that can be grow outside in summer my Dutch climate or even species that can only grow inside with temperature and/or humidity. Some Dioscorea make bulbils or airpotatos that are smaller and easier to ship than tubers.

Martin. I think the tuber that I bought this weekend as Iron Stick is one of various cultivated forms of D. polystachia. But it is always good to compare with other ones especially if they will come available in a future EU exchange.

I received this Dioscorea discolor early this year from a PBS EU exchange. After staking the the main shoot aborted it took awhile but now some side branches do even better To my surprise the big leaves on the main shoot are much bigger but also have a different color. Guess that is just young versus old growth. Given this success I want to grow other Dioscorea species besides the ones I started from tubers I found in Asian food stores. Anyone growing these as well (in the EU) and want to share a tuber (possible when plants go dormant)?

Caladium hybrids. The problem for me is not to get the tubers start growing in spring but to get them overwinter without drying out. Any pointers to increase my success rate of 30-40%?

Those Eucrosia seeds sprouted within 3 days after floating. Guess I used a bottle of holy water instead of water from the tap.
