Iris are popular plants for the sunny garden, but what if you want to grow them in shade? Iris cristata ‘Alba’ fills that role very nicely. It grows best in part shade with a reasonable amount of moisture.
This plant is much smaller than your common garden iris, but it puts on a nice show early in the season, well before the bearded iris. It does not need to be dug up regularly, and so far I have not seen an iris borer on them.
