Venus Fly Trap Dormancy – FlytrapCare.com
Many inexperienced Venus fly trap growers make the assumption that Dionaea muscipula are tropical plants and that they should be kept in warm growing conditions year round. However, the truth is that Venus Fly Traps are very hardy perennial plants. This means that they grow and bloom over the spring and summer and then die back to a small rosette every winter, growing back in the spring from their energy reserves saved up in the rhizome or rootstock. Venus Fly Traps go dormant naturally in the fall when growing outdoors. They can withstand frost and light freezes. However, freezes that last an extended period of time can kill Venus Fly Traps.
