Thanks for replying lorax, the leaves do resemble clivia but IÃ‚Â´ve finally found it on Wikipedia..... , itÃ‚Â´s called Haemanthus albiflos. https://en.wikipedia.org/wiki/Haemanthus_albiflos
As it says in the link, they thrive on neglect...I water them once a month if I remember and they grow and multiply in their plant pots without any help at all. One is supposed to re- pot all the offspring but there are so many that IÃ‚Â´d have no floor space left at all if I did so. One year I repotted some and the others I left in a plastic bag without soil in the garage because I felt bad about throwing them away, they were still alive and well months later!! Over watering seems to be the only thing they donÃ‚Â´t like.
