Gardening Quiz - Houseplants - Houseplants 3 (Questions)

This is the third quiz in the Education Quizzes series on houseplants and it concentrates on seasonal and festive plants. More often than not these are flowering plants that are given as presents at Christmas and other celebratory occassions.
