Answer: Although they are listed as perennials, Iceland Poppies are usually treated as annuals in hot summer areas. They are native to Siberia and prefer cooler temperatures. Here in zone 5 it is unlikely that they will survive more than one year. It is the heat that does them in so hot spots in the garden should be avoided. Keeping the ground cool with mulch may help keep them going. Iceland poppies like poor graveley soil however we don't have that kind of soil around here so you might try mixing some commercially prepared cactus mix into the planting hole (or filling a container with cactus mix and planting your Iceland Poppy in that).
