I have extreme allergies and asthma to more plants, some animals, insects and some medications than I can describe here. One holiday plant that is always everywhere I go is Poinsettias, even into grocery stores at the front entrance or a restaurant. I will immediately start sneezing and getting stuffy, then coughing from this beautiful plant. I have to ask my friends, before visiting them of they have this plant in their home. If they do I have to excuse myself from any visits. Close friends know that a day before I may visit to put their plant into another closed room, but even then I am reluctant to have them go out of their way for just me.
