Step-by-step explanation:
In the Canterbury Tales, the host proposes various plants to the characters as part of an imaginary setting or as metaphors in the poems. For example, in 'The Miller's Tale,' the host proposes making beds of roses and fragrant posies. In 'The Lady of Shalott,' the reaper whispers about the fairy Lady of Shalott by the moon. In 'To Autumn,' the poet describes the season of mists and fruitfulness, including images of ripening apples and hazel shells. These plant references are used to create vivid imagery and evoke different emotions in the reader.
