Virginia, welcome to the iris forum!
'Bluebeard's Ghost' is my favorite white SDB, though I've had trouble getting it established in my garden.
'Cat's Eye' is a very popular reddish SDB that grows well in many locations.
Do you live near a local iris society? Many clubs have rhizomes sales where you can acquire varieties that grow well in your area. Here is a link to the local American Iris Society affiliates in your region:
