  Re: [Aroid-l] Leaf fertilization - A.titanum 'ghost'

My limited experience is also with other genera, and is exactly as George
described - 1 or perhaps 2 seasons of decline and then disappearance. My very
unscientific impression is that this happens more often with selfings, which
would be completely unsurprising to me but is certainly not required. A batch
of hemerocallis seeds sent to me long ago by Phil Mueller germinated almost 40%
"albinos", the highest percentage I've ever seen. I had one variegated
hemerocallis which developed the habit of putting up some completely white
fans and some which displayed the "normal" variegation. I hoped this would
enable it to grow very slowly and still look spectacular, and it did survive
for 5 or 6 years, but it hasn't appeared this year and I fear the worst.

The cactus & succulent people graft non-chlorophyllous plants, as David
suggested, and now have quite a stable of them (which people seem to love or
hate). In your case, as the leaf is transient, you'd actually probably want to
graft a leaf with chlorophyll onto the stem to provide the tuber with food.
Not only do I have no idea how you'd do this with just a leaf - is it even
possible? - it would obviously not preserve the unusual appearance, and what
leaf would you use?

I have a desultory interest in this, enough to make me search the web
occasionally and watch the mailing lists in case someone comes up with an easy
way to keep these plants alive, but not enough to make me get out the big guns
and try things myself. They seem to fascinate a lot of us, and there's been
discussion on several lists about possible approaches - I seem to recall a
particularly long-running discussion on the clivia list, and you might search
those archives to see if anyone came up with an answer.

Good luck, and please let us know if you are able to keep it going.
