This poem also belongs to a category of poetry which was renowned in this era called "Carpe Diem," or Sieze the Day poetry. The general message was to hurry up do something--live life to the fullest now because we don't know what will happen tomorrow.
Herrick's message is, "ladies, while you are still young and beautiful, hurry and find a husband. If you wait to long, you will dry up and become ugly and no one will want you."
Marvell's "To His Coy Mistress" and Donne's "The Flea" also belong to the Carpe Diem faction of poetry.
“To the Virgins, to Make Much of Time” is composed of four stanzas, each consisting of four lines of verse. Each stanza is composed of a single sentence. The poem employs end rhymes, the rhyming pattern being abab, cdcd, efef, ghgh.
He also uses the trochaic foot, which is a unit of two syllables with the first syllable stressed, and the second unstressed. The first line should read like this:
ther / ye rose / buds while / ye may.
