Re: CULT: ?rate of increase

Thanks Vernon.  That helps a lot.  Sounds like this one is probably too
slow by those standards.

I'll get a few folks to try it in other climates & see how it does
elsewhere, & will go check the mother & grandmother rhizomes growing
here to see what the range has been the last couple of years.

Then again, if the lower range is to make sure a cultivar doesn't die in
a bad year, maybe extra durability in bad years compensates.

<According the AIS Handbook, an iris should have an increase of 3 to 5
each
                   year. Less than three and on a bad year you can end
up with none and more
                   than five and it will over grow itself before three
years are up. If your
                   increase of double is for one year due to weather,
soil conditions, whatever
                   and other years it is with in the 3 to 5 quantities
that is another story.
