Dark green dragons, once they mature, appear to become an entirely different species. However, this isn’t true. Rather, they burrow underground and get nutrients from their vines. These vines are sometimes referred to as Dragon Grass. These dragons are very violent, and will use their vines to capture, kill, and eat anything that moves, as well as nearby plants. Luckily, their range is limited and they cannot use magic. Dark green dragons tend to be easy to spot since they usually kill all plants around them and thus are usually surrounded by a large clearing.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Due to the genetic mutation which produced daffodils on his vines rather than snapdragons, Dark Thorned Daffodils was one of the few Vine dragons to escape being uprooted by Xanth Tangle Tree. He has since moved to his own clearing.

Unlike other Vine dragons, he seems to prefer scavenging to hunting. He uses his vines to dig up buried kills from other predators. It has been theorized that this is an adaptive trait taken to lull other creatures into a false sense of security: most Vine dragons are easily spotted by their large clearings, which other creatures quickly learn to avoid.
