Every fall I think I'm going to find time to plant some bulbs which would make me ever so thrilled come spring when the flowers pop up. But no. So what's this I hear about summer bulbs? You can plant bulbs in spring that will bloom in summer!?!? What a concept! But does it really pay off?

Have any of you ever planted gladiolus, dahlia, calla lily, caladium, crocosmia, agapanthus or tuberose bulbs in spring? Any tips you can share with me?
