ahem.... jabriolis does not exist in
nature, just on the internet as
'Trollus extremus'

Not all plants that are supposed to
flower, will flower (usually as a way to
teach us to be humble).

And you may not have planted it but
it may have come in as a hitchhiker
on another plant. Right now I have
a pond full of hornwort which came in
as a tiny sprog in a lily pot.
Also had a reed take over a deck tub
full of cattails and did not plant that
either. And then there was the bladderwort
in the frogbog, I think that came via birdy.

I think Nature does this on purpose
to drive us crazy. The story of my life...
