T'iil refers to an Alderaanian plant that possessed a sweet aroma and bore flowers. Its blossoms had a trumpet-like form and displayed a bright yellow hue. Upon Naboo, large herd creatures like shaaks aided in the pollination of the t'iil.
An extract derived from the plant's central root was thought to alleviate throat irritation. The plant's foliage was processed to brew a calming beverage. The solitary nectar droplet found within the t'iil was collected and employed in the production of l'lahsh.
During the Imperial Period, T'iil seed cake was a common treat within the Aldera Royal Palace. Furthermore, the T'iil Blossom Homes structure, located on the planet Delaya, provided shelter for Alderaanian evacuees following the Galactic Empire's destruction of Alderaan.
