Hi,

I have a wonderful bearded Iris called 'Victoria Falls'. It think it was
introduced 25-30 years ago. I grew it before in Alabama, and enjoyed it
because
of the color, the rebloom, and the ease of care. It took care of
itself--never
seeming to need water and only a top dressing with aged manure once or twice
a year.

Here in Conroe, zone 9a, it has been in the ground for about 2 years in full
sun, in good-draining not-too-rich soil. It hardly blooms and does not
rebloom. It grows well, and seems happy enough, except for July and
August when it
seems to sulk (I suspect it is heat).

So, what can I do to make this plant do better? I have a few other
reblooming bearded Iris hybrids, and they almost never bloom. They grow
OK, but don't
bloom. Do they need a colder winter? The past 2 years temperatures have
only
dropped to 25 F.
