> Thanks Chuck, yes these are very short and grow from bulbs much 
like dutch iris do. I really didn't know what they are. I think they 
came as a free gift when I bought something else. They come up every 
year and I always wonder what they are until they bloom.

On second thought and after relooking at the photos I would have to 
take back what I said. The standards are too large for setosa. There 
is some resemblence to dwarf siberian but another possibility is 
Sibtosa, a cross between setosa and siberian. Some further 
information could help with identification.

1)Seed pods and seeds. Versicolour will hang, setosa and siberian are 
upright. If no seeds then very likely Sibtosa. Differences in seed 

2)Leaves, thickness, presence or absence of water plant webbing. The 
best way to tell this is to comparae with leaves of versicolor and 
pseudacorous (which have webbing) versus spuria and siberian that 
don't. Spuria leaves are usually very wide and very stiff.

3)Root system- size and shape of rhizomes and how they increase.

4) Wetness tolerence. Versicolour, siberian and setosa have a high 
tolerence of moisture, spuria don't. They all will grow in very dry 

You do have a puzzle here.
