Yes the Iris leaves last a maddeningly long time, even longer than the tulip leaves. We hid them with Wave Petunias planted in May. We have daffodils with the tulips, forgot to mention them.
We have some tulips and crocuses that come up every year that were planted +20 years ago. They are shorter early-mid short reds with yellow centers. Even when we planted +300 new bulbs in 3 layers around them they still came up.
Will it cause any problems for the summer-fall perennials to have tulip bulbs planted between them? Will it limit the perennials' growth?
Has anyone here had Giant Pansies blooming in coastal NY winter weather December-February? We'll definitely give them a shot, but likely also plant bulbs, as one shouldn't interfere with the other.
