Re: Irises for northern MN
Ellen -- Please post those addresses to the whole LIST of iris that are being
sold in colder climates -- Are the rhizomes you are testing coming from
growers in northern climates, or are they cultivars proported to grow well
in the north?? The Q goes to the difference in reputation of the cultivar
vs actual conditioning of the rhizome to the northern climate prior to sale.
This could be an interesting project for a LIST -- another group has some
cultivars (of another plant) which are being trialed around the country
to test for zone hardiness. And another trial to find out whether it makes
any difference where the particular rhizome was grown in the year prior to
its sale would be interesting and useful.
