There are two quite different plants called celandine, and they are from two quite distinct genuses. Lesser celandine (Ranunculus ficaria - a member of the buttercup family) is a nasty little thug, spreading like mad in lawns via seed and bullets. I am still fighting a battle with it in MIL's garden. this is year 3 and I have just zapped tiny shoots, and will do so weekly for teh next two months. I will not let a single one flower, so that no more seed is produced. I am nearly there in getting rid of it, maybe this year, maybe next.
The other is the Greater Celandine, Chelidonium majus, a member of the poppy family. It is grown as a herbal / homeopathic plant in wild gardens, and spreads readily by seed like any poppy, but does not invade lawns like the lesser Celandine, and I bet there are times when it wishes it had a different common name!!!
