i am doing a project on a lily and i need to know if it reproduces asexually, sexually or both

a lilium -lily
trumpet lily

The Tiger Lily can be reproduced both asexually and sexally (requires another plant, the lily itself is self-sterile)

To determine if a lily reproduces asexually, sexually, or both, you can research the specific species of lily you are studying. In this case, you mentioned two types of lilies: Lilium lilies and Trumpet lilies.

For Lilium lilies, they are primarily reproduced sexually. Sexual propagation occurs when pollen from the stamen (male part) is transferred to the pistil (female part) of another flower, leading to the formation of seeds. This method usually requires another plant since most Lilium lilies are self-sterile. You can find more information about sexual propagation specific to Lilium lilies at the provided link:

As for Tiger lilies, they can reproduce both sexually and asexually. Sexual propagation is similar to that of Lilium lilies, but Tiger lilies are also capable of reproducing asexually through various methods. These methods may include bulb offsets, bulbils, or division. For a detailed explanation of asexual propagation techniques for Tiger lilies, you can refer to the provided link:

Remember to conduct additional research to validate the information and gain a more comprehensive understanding of the reproductive processes of the specific lily species you are studying.
