One species stands tall in the vast realm of carnivorous plants. Meet Drosera auriculata, commonly known as the Tall Sundew, unlike other drosera species that grow in low-lying rosettes. This captivating carnivorous plant has earned its name for its impressive height.

Tall sundews are recognized for their slender, elongated stems that can reach remarkable heights, often standing above other sundew species. The species can be found in both dry and damp places in Australia. The spot where I observed this species is the driest area I have ever seen a sundew in!

Like many sundew species, the tall sundew relies on both its sticky leaves, and a trigger response that envelopes the prey as it gets digested. A characteristics that is also utilized by its closely related species, the famous Venus-Fly trap! Below we see close-ups of leaves and their prey.

Utricularia

Utricularia, or more commonly known as Bladderwort, is a genus of carnivorous plants that are semi-aquatic to terrestrials. Their modified leaves underwater can catch small insects and even algae. Which technically makes them an omnivorous plant! You can find more information in this blog post. InDefenceOfPlants is an excellent source of plant information. 

Shown above are two species I found in bloom, stripped bladderwort (Utricularia striata)[1 and 2] and the horned bladderwort (Utricularia cornuta) [3,4 and 5].

Here in New Jersey, you can find them growing in bogs. New Jersey hosts more than 10 species of bladderworts, some rare and threatened. They are hard to spot for most of the year, but in mid-summer, they pop out a pretty yellow flower blooming above the water surface. Clustered together, they put on quite a show.
