Plants from a number of genera including Dionaea, Drosera, Pinguicula, Sarracenia, Nepenthes and Utricularia are the main types.
Photos on website are in most cases representative of the plants mature size and not necessarily the exact plant you will receive. Nepenthes, in particular, may not develop traps in the shop due to specific environmental requirements. Sizing is approx but Nepenthes are sized xs 2-4cm, sm 5-9cm, med 10-14cm lrg 15cm and up.
Requesting a photo of the plant before you purchase may limit any surprises or disappointment.
