Chances are you do really have Ferraria crispa.  They produce multiple corms
like crazy.  I repot mine every couple of years; if I wait longer the entire
pot will be filled with corms.  Fortunately, they do not spread
horizontally, so I don't think they are an invasive threat.


They are pretty easy to bloom in typical summer-dry mediterranean
conditions.  As others have suggested, leave the corm clumps intact and
you'll get bloom sooner.  I have bloomed them in 8-inch pots, with the tops
of the corms an inch or two below the surface.  Bigger pots may work better.
Use very well drained soil.


I have a number of other Ferraria species, and many of them are much harder
to make bloom here.  I'm not sure what the problem is, although a number of
them are desert species and it may be too wet for them here in winter.


Good luck, and let us know what the flowers look like when they bloom --
they are quite variable.
