If you find this interesting, I strongly recommend the book _The Light Eaters_ by Zoë Schlanger [0]. She discusses this finding as well as other sense-abilities of plants. Recent science has found pretty amazing things.

If I recall correctly: flowers are often shaped like dish antennas to collect sound vibration, and plants can distinguish the frequency of wing beats of their preferred pollinator from frequencies of other insects, and will act only for their pollinators.
