Tet. Pigment Of Imagination is a rare opportunity to get into a ground floor area of tetraploid hybridizing. Tetraploid Color Changers. I have several dozen now. Mike Holmes has also bloomed first generation Tet. Color Changers out of Tet Pigment Of Imagination. Diploid Pigment Of Imagination is a much admired daylily along with its offspring. I believe Tet POI and kids will be equally admired.
