Re: [Aroid-l] Ulearum donburnsii

Interesting point. I had tried that method on Dracontium a few times with no success. Now I want to try it on some other tuber forming New World taxa.
Yes, I basically used the same=C2=A0technique, but I think I started them in just water, moving them to sphagnum moss when the first root appeared.=C2=A0 I may have used bottom heat, but I do not recall. Too many years ago!
Happy days, Christopher Christopher;
Agreed, but all the genera you mention so far are old world genera, while Ulearum is a new world genera. This is what makes its leaf propagation unique.
I did not know about it working on Nephthytis and Hapaline, do you just propagate it in the same manner?
All the best,
That is really cool!
I had U. donburnsii=C2=A0 many years ago. It did quite well for me and bloomed regularly. It also divided for me=C2=A0several times, and I was able to give away=C2=A0many plants. One winter the heat went out in my greenhouse, and that was it.
I have used that method to propagate Amorphophallus, Sauromatum, Typhonium,=C2=A0Nephthytis, Arisaema, Gonatopus, Hapaline,=C2=A0Dracontium, and Ancomaenes.=C2=A0
Ancomaenes can also be easily grown from large broken off roots.
Happy days! Christopher
Hi all,
Ulearum donburnsii Croat & Feuerstein is a tiny neotropical aroid only known from Ecuador near the eastern border with Peru. Surprisingly it can be propagated by cutting off leaves at the petiole and leaving it in moss/soil. Over time a rhizome will form at the cut. Other Ulearum can also be propagated this way, I do not know of any other neotropical genera propagatable by leaf cuttings.
Photos are of an adult flowering plant, leaf progress at a few weeks, 4,5 months, 10 months and a year later.
All the best, Nils
