interesting, as I am certain the plants I saw were blooming in February and,
other than a short rest from flowers in Summer, have a long season judging
from the seed pods. It may be that they are actually ever-bloomers, but I
have coincidentally seen them non-blooming in Summer.  Like I mentioned,
mine have yet to flower and seem to prefer the cooler season for growing.
Alberto mentioned that they are easy from seed, which has not been my
experience, either.  In fact, I find most Irids difficult to germinate and
grow on.

When I was in Florida last April-May, I saw a few plants blooming, but most
seemd to be finsished for the season.  I even transplanted a few for my
sister.  There they were growing in almost pure sand in full sun. As most of
Florida is actually pretty dry for Summer, it may be that the plants simply
take advantage of the warm, wet months and thus I've encountered them
blooming in Winter- Spring.

my problem with wet is in the Winter.  We rarely have a true deep freeze in
Cologne, maybe two weeks in February, but it is wet from December to May and
many plants rot if not protected against the standing water and temps just
above freezing.  I have even made raised and sloped beds to aid drainage,
which helps considerably. Of course, so no one misunderstands, the plants
are protected from frost in an enclosure, but I give them as much fresh air
as possible in Winter.

I hope to bloom them at some point and post fotos.

April now. Indeed bicolor is more fioriferous, being the stalks much
branched even if flowers last just one day. Grandiflora has larger flowers,
which last a couple of days (not in the hottest days) but to have a good
show the plant must be large. Bicolor performs much better in partial shade,
while grandiflora in sun. Anyway, they need a lot of moisture in summer and
I can't overwater them.
