Re: propagating E. uruguayensis

Dirk, I looked at your picture, and the plant still looks quite small 
to me, based on the sizes of the surrounding plants, even though it 
has quite a few leaves.  It can produce submersed leaves 18 to 20 
inches long and floating leaves between three and four feet long, 
including petioles.

I don't have this species now, although I have had it for many years 
on a long day (14 to 16 hours of light a day), and it has never 
produced a flower stalk for me.  So, I would try shorter days.  It is 
now grouped in the same species with the former "red horemanii" and 
"green horemanii", but, while the latter two seem closely related, 
the former seems really different.  If anyone knows how to get red or 
green horemanii to bloom, perhaps the same conditions will work with 
the narrow-leaved uruguayensis.  John Pitcairn got red horemanii to 
bloom in backyard plastic swimming pools (about 6 feet in diameter 
and 2 feet deep) in San Diego.  I think it was in the winter that I 
saw them blooming.

If you grow it for several years, it will have a long enough rhizome 
so that it can be pulled up and cut into pieces about 1.5 inches 
long.  Each piece will produce a plant.  This is slow, but the only 
alternative if it won't produce a flower stalk.
