Oxalis adenophylla

Hi, Rodger, now you've added to the puzzle.

I thought Diane's suggestion of keeping it dry in summer must be the
answer, because I hadn't done that. Jane's growing it with extreme drainage
doesn't appear to be what you do in your garden. I've tried it in various
spots,
all with good if not extreme drainage, for instance in a pot above of a lily,
edging the sidewalk by/under rhododendrons, and so on, and they last for a
while
if not flower heavily, then no more. Your climate should be similiar to
mine, and
the oxalis here were never put in full sun.
So, do yours get dry in summer?
