. It refers to a plant’s ability to respond to variations in the length of day and night.Christmas cacti are classified as “short-day” plants, which means they require long, uninterrupted periods of darkness to trigger their flowering mechanisms.
During the dark periods, the plant starts producing a hormone called <a href=«https://www.google.com/url?sa=t&rct=j&q=&esrc=» https: target="_blank" rel=«noopener»>florigen
