rooting plants from leaves

From: Kathy Upton <SKKUPTO at UMSLVMA.UMSL.EDU> on 1997.11.30 at 23:42:45(1668) Dear aroid propagators: I have found that the genus Chlorospatha can be propagated from a leaf. By leaf, I mean the petiole and leaf blade. I placed the petiole of Chlorospatha croatianum in a peat and perlite mix in a warm humid growing area and it sprouted roots after 6-7 weeks. It is now sending up a new leaf. I realize that a few other genera can be propagated in this way, such as Gonatopus, Zamioculcas (from leaflets), and also Amorphophallus. But are there other genera that have been propagated in this way (not by tissue culture)? I'm planning a little experiment here with Jane Whitehill and would like to know what genera have previously been rooted this way and what you all might suggest that would seem the most likely to work. Thanks! Kathy Upton +More University of Missouri-St.Louis
