Lily plants exhibit both asexual and sexual modes of reproductions. Asexual reproduction is the mode of reproduction which requires a single parent to produce numerous offsprings. In lilies vegetative propagation is the asexual mode of reproduction in which bulbs, scales are used to produce new plants. The lily plants can also be grown by tissue culture. In lily plants the asexual reproduction requires only one flowering plant. Sexual reproduction also takes place in these plants but male and female parts are present in different flowering plants. Lily plants are diocious.
