Alberto, Similar to the "Rembrandt" tulip cultivars that were grown for the beauty but ignored of their sickness? Also, Chimeric tissue in plants meaning two sets of genetically different cells or is it different? Jude, A friend of mine had a Hippeastrum papilio that threw out a variegated pup, this bulb was tested for viral infection several times and was negative and eventually reverted to a normal green plant in due time. I had the same variegation in Hippeastrum stylosum that was also free of viral infection and would occasionally contain all green leaves.
