I looked up BLACK LADY in the checklists and parentage quickly goes back
to a dead end.  Can you give me names of some others?  Anybody onlist
familiar with MTBs want to speculate where the baldness in the MTB
variegata patterns comes from?  Based on the 3 clones of I. variegata I
grow, it isn't from there - they keep their leaves here, in spite of
gravel soil, months of temps in the 90s and no rain. Not that they are
happy about it!

Seems like somebody posted that all/most of the dwarf species shed their
leaves and shut down under stress (drought/heat/cold).  I wonder if all
the dwarf species are as variable as aphylla seems to be here.  Or if
all the aphyllas I got this year will keep their leaves once they get
established.  Do you grow other dwarfs that behave different from
attica?
