CULT:Katherines white iris

From: "Dan and Katherine Roberts" <dankat@mail.myriad.net>

Hi Jan,

	Thanks for the suggestions.  I did buy several irises at once.  
However, I know where I planted each of them.  Some of them did not 
bloom this year.  But, I suspect the bad summer and odd winter we had, for 
them not blooming.  I'm 95% sure I have the right plant.  I don't use 
roundup, so that wouldn't have been a problem.  I don't recall any frosts 
before it bloomed, but that's entirely a likely cause.  I don't recall if the edge 
of the flower looked fried or not.  

	I did try looking this problem up on a number of sites including the 
mallorn site, but nothing was coming up for me.  So, I either wasn't using 
the right key words or something.  

	I think what I will do though, is move all the iris in this particular 
bed this fall and see what happens next spring.  And oh dear, this bed is 
going to be empty...  Gee...  guess I'll have to buy a few more irises to put 
there <wink>.
