Chlorophytum comosum
A houseplant with long, slender curving leaves which usually have a white stripe down their centre. They will live happily in most well-lit indoor situations or in greenhouses, and need regular watering (but don't drown them). They reproduce asexually by sending out shoots that have little baby spider plants at the end of them (note, this may not be the biologically correct term!) and when these shoots find soil they start to grow on their own.
