RE: Iris Species for Cold Climates

Hi Bob:

We grow setosa, cristata, pseudacorus, and hookeriana successfully.  Our
soil is predominantly clay.  We had also tried lactea, missouriensis,
musulmanica, virginica, laevigata and vivescens.  They didn't make it
through the first year.  We may try again sometime and mulch them.
