Is a daffodil annual biennial or perennial?

No, daffodils are perennials. When you plant the bulb in the fall, it remains dormant until spring when it shoots up new growth. The bulb stores up food made by the leaves through photosynthesis and uses it to send up shoots again the following year. Bulbs multiply underground and can be separated and planted in the fall to start new daffodil plants in other locations.
