A lovely and unique habit of tulips, they are the only cut flowers that keep growing in the vase. Tulips are really responsive to light, and they bend, twist, and elongate towards the nearest light source, like a window.
Tulips have a special tissue called Xylem that allows them to take in water even without roots. The cut stems are filled with energy and hormones that cause the blooms to open and the stems to grow. Sometimes, several inches.
And that is the botany lesson of the day.
