Here is My Current Ranking of most of the Carnivorous Plant Genera in a Tier List, along with explanations! What do you all think?

Tentative Carnivorous Plant Tier List (MY OPINION)

D Tier:

  • 14th Place - Aldrovanda - "The Waterwheel Plant": Firstly, I do not really know much about this plant, but from what I do know it's carnivory is displayed in a manner not as easily perceptible to the human eye, making it less obviously a carnivorous plant, which is of course a draw to all the different genera. Additionally, the color variation and plant structure is not as interesting as any of the other carnivorous plants, in my opinion. I would not really have thought it to be carnivorous unless I truly examined it closely, and due to the fact that it is aquatic, this is possibly a more difficult task to undertake without harming the plant.
  • 13th place - Brocchinia - "Carnivorous Bromeliads": In addition to the waterwheel plant, this species is not obviously seen to be carnivorous, and the color variation is not very diverse (although more so than the former). The plant structure is unique, which along with the color does bring this plant out of last place, but it still remains in D Tier due to the lack of very interesting features.

C Tier:

  • 12th Place - Utricularia - "Bladderworts": Bladderworts also appear to be non-carnivorous at first glance, and require a magnifying glass at least to view the traps. Additionally, not much is to be seen besides the flowers. The beautiful flowers do keep this plant out of D Tier, as well as the complex structure of its traps (though not easily seen). As a clarifier, I still like bladderworts, along with all of the carnivorous plants, but for the sake of this tier list the bladderworts will (under my opinion) be placed into C Tier.
  • 11th Place - Roridula: It was somewhat difficult to decide whether or not this plant should be placed in this section of the tier list. Due to the fact that the typical carnivory of this genus is unconfirmed, it does not have the appeal that would bring it above C Tier. However, it is still a unique-looking plant with some vibrant colors. The relationship it has with certain insect species is also interesting, but still, I believe that the plant does not have the same beauty of the plants above it on the list.

B Tier:

  • 10th Place - Darlingtonia - "The Cobra Plant": I believe this species definitely deserves at least B Tier because the pitcher traps have a strong ability to grab my interest. The curvature on the cobra plant is striking, though its color variation and vibrance is somewhat lacking. However, it is still a likeable plant, but does not hold the same place as the others in my opinion.
  • 9th Place - Byblis - "The Rainbow Plants": These plants are rarely sold and supposedly difficult to cultivate (I do not know this from experience as I have never grown rainbow plants). On the other hand, their glistening mucilage adds some allure to them. I appreciate their appearance and their true carnivory, but their relative lack of variety in size, color, and shape brings them below A Tier.

A Tier:

  • 8th Place - Drosophyllum - "The Dewy Pine": Similar to the rainbow plants, the dew of this species is striking and its ability to grow to a large size is impressive. The fact that the plant has a sweet scent to it makes it more appealing to me as well. However, like the rainbow plants, it is apparently difficult to grow and it does not have much variety. Its good qualities still bring it all the way up to A Tier, and, at this point, I believe the plant genera have begun to be quite amazing.
  • 7th Place - Heliamphora - "The South-American Pitcher Plants": These plants have a beautiful shape and hue to them; they appear smooth and glazed, which looks wonderful in my opinion, and their pitcher traps are also intriguing. However, the variety and shape is not as variable as some other pitcher plant genera.
  • 6th Place - Pinguicula - "Butterworts": These fly-paper leaved plants have a wide spectrum of colors and pretty flowers, perhaps the best-looking flowers of all the carnivorous plants. Also, the fact that they have a natural mechanism similar to the human invention of fly-paper used to digest prey is very interesting, but still less so than the higher plants on the list.
  • 5th Place - Cephalotus - "The Australian Pitcher Plant": This plant features adorable little pitchers with striking bristles and bright colors, along with deeper ones as well. The clumps this plant forms are also amazing (seeing all of the little traps in one place), which brings it high up on the A tier. The others above it still appeal to me more, however.

S Tier:

  • 4th Place - Sarracenia - "The North American Pitcher Plants": These pitchers can reach tall heights, which make them strikingly noticeable, and they have an interesting trapping mechanism with the nectar on the lid leading into the myriad of digestive enzymes at the bottom of the pitcher. Their colors are beautiful, ranging from the stark white of S. leucophylla to the curved, purple pitchers of S. purpurea. These plants have continued to amaze people over the many past years. There is still one pitcher plant genus which I believe is superior.
  • 3rd Place - Dionaea - "The [Famous] Venus Flytrap": This species of course deserves to at least be in the top three carnivorous plant genera of the world, due to the captivating rapid-closure of its traps and the teeth-like cilia on the edges of each trap. It bears resemblance to a monster for insects, dangerous, but hard to resist engaging with. The ability of the flytrap to ensnare insects so quickly will never cease to be fascinating to me, as I assume most of you would feel as well! Also, the deep red found within many cultivars' mouths is beautiful and creates a sharp contrast between the bright green of the rest of the plant. The shapes of the mouths and the trigger hairs within them are undeniably wondrous. This placement was difficult, but ultimately I believe the two genera above it are even more amazing.
  • 2nd Place - Nepenthes - "The Tropical Pitcher Plant": These plants, with such a stunning variety of species of different shapes, sizes, and colors, are absolutely breathtaking! This was a type of carnivorous plant I fell in love with at first sight; in fact, this genus drew me towards the hobby in the first place. The sharp teeth of N. hamata and the large pitchers of N. truncata and N. rajah stand out to many, including myself of course. These specimens are fascinating and deserve much recognition, second only to one, I believe.
  • 1st Place - Drosera - "The Sundews": The attractive, shiny dew drops of nectar on this species, with their dramatic movement around prey over time, and the massive variety of species is amazing! This genus is unforgettable when it is seen, with its complex digestive processes and its gorgeous, sticky leaves. Although this list may change over time, the sundews hold a special place in my heart as my number one variety of carnivorous plants!

Now, what about all of you guys? Do you agree with my list? If not, what changes would you make?
