Venus flytrap dormancy question.
I have one venus flytrap that has grown normally all this summer outdoors and is showing evident signs of being ready to go dormant this fall so far. i also purchased a few plants around the middle of october and they all had strong summer growth. So my question is , was my purchase a waste of money? and i have both my regular dormant ready plant and the active growing plants downstairs near a window in a unheated room for this winter, making sure they are watered and dead growth is removed. is there any insight or perhaps something im doing wrong. Thanks in advance.
