Question:
Why do tulips continue to grow after they are cut?


Replies:
Because the stalk needs to grow from the bulb below the soil surface and continue upwards, the tulip has chemicals called auxins that help the stem/stalk to grow. Even after cutting, the plant cells inside of the stem continue to divide and elongate.
