Got a few of these Iris Cristata from Lowes. The information about them on the web is a little confusing; but it is supposed to flower in April-May, and is supposed to be attractive to bees and hummingbirds. Quite important, it is supposed to do well under trees. We'll see how it does, given I just planted these, any results are at least an year away. This species is not native to New Jersey, and the best I can find is that it reported to do well in New York, and in South Jersey, and so perhaps it will do well in this middle region.
