Summary
[edit]DescriptionOxalis Triangularis Photonasty Timelapse Darkening.ogv |
English: Oxalis triangularis (also known as the love plant or purple shamrock) is a classic example of a plant which responds with movement to external stimulus. The leaves open and close in response to varying light levels with the result that they are open during the day and close at night. This is true movement (i.e. not growth) and is non-directional with respect to the stimulus making it an example of nastic movement towards light: photonasty.
