Hi, I have tiger lilies that I have had for 15 years, and now half of them have lighter plants and grow only yellow lilies. I thinned them out last year, and pulled out the light ones, but new ones grew from the smaller bulbs. Why are half of the plants and flowers yellow and bloom later than the true tiger lilies?
