Re: Ulearum donburnsii

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,

Nils

That is really cool!

I had U. donburnsii  many years ago. It did quite well for me and bloomed regularly. It also divided for me several times, and I was able to give away many plants. One winter the heat went out in my greenhouse, and that was it.

I have used that method to propagate Amorphophallus, Sauromatum, Typhonium, Nephthytis, Arisaema, Gonatopus, Hapaline, Dracontium, and Ancomaenes. 

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
