My plant has been growing well in the unheated conservatory.
This is Drosera capensis alba - Cape Sundew

It is one of the easiest to grow and is happy with the heat in Summer and the cooler / cold temperatures in the Winter. The main care point is keeping it moist all the time. I always keep the saucer topped up with rain water. During the Winter I also use the water from the de-humidifier I sometimes run in the conservatory.
The slender leaves are covered in a mass of very sticky globules which catch any unwary small flies which land on a leaf.

From experience I can vouch that they are very sticky.
