I'm still growing hippeastrum,although far fewer,since I've destroyed about two thousand due to Moasic infestation..I still find them occaisionaly. The ones I still have either are resistant,immune or haven't gotten it yet.I have been crossing with papilio and others trying to develop resistant hybrids.I don't know if papilio is actually immune,or if it just never shows symptoms.I hope to eventually have some virus testing done to determine some of these things.I do have some pretty hybrids of papilio,but no camera.
