Marilyn, oldies are awesome for growing among other plants. Many have a grace and charm, a subtle beauty, that mingles more softly than larger, flashier modern blooms. Some will even thrive among ground covers, like Indian Chief. Clumps of Iris arising from a thick blanket of pink evening primrose or silvery leaved Lamium dotted with pinky purple blooms is wonderful! A lot of my oldies flower well in partial shade too. I love that there is an Iris for nearly any garden situation!
