Answer: It sounds as though some of the hybrid corms died off and the more vigorous corms - in this case pink - took over the bed. You'd be doing your glads a favor to dig the corms when the leaves begin to yellow and store them in a cool, dark place until spring. Then plant them back in the garden. You'll lose fewer corms this way, and will have nice healthy plants that will present you with new baby corms, to increase your stock.
