Which plant from the following is a flowering herbaceous perennial?

• A. Ageratum
• B. Zinnia
• C. Marigold
• D. Daylily

Answer: (D)

A plant that is a flowering herbaceous perennial lives for several years, has soft, non-woody growth, and blooms year after year from the same crown. The daylily fits this pattern: it has a perennial crown that survives winter (or dry seasons) and sends up new leafy shoots each season, producing plentiful flowers on tall stems. It dies back to the crown and regrows, rather than needing to be replanted each year. The other choices are typically grown as annuals in temperate climates because they complete their life cycle in one growing season and don’t persist as established perennials. They do produce flowers, but they aren’t reliably perennials in common garden conditions. So the daylily is the best fit for a flowering herbaceous perennial.
