What you have is know as an 'orchid' cactus, most open at night...have a lovely fragrance...most only last til the next morning to 3 days.
They propagate very easily..if you thin out the leaves..take some and pot them up to get more.
Look it up..I really love them..I have 3 varieties...hope it helped...look at my album "Cactus 'n Succulents" to see the flowers of my lit' collection
