Pxiwll - Sharp plant
Cynaroidia discolor -Artichoke-like, multicolor
|Behind the scenes|
The hermit bud (Na'vi name: pxiwll meaning "sharp plant") is similar to the thistle bud and lionberry, the hermit bud grows a cluster of many flowers (inflorescence), similar to the sunflower family on Earth. Samples of the hermit bud were taken to Earth with the thistle bud and lionberry to determine their genetic origin and possible source of introduction. This plant has evolved a spiny cactus-like center, presumably as a defense against herbivores that would harvest the seeds. The seeds are large and edible and good source of protein and oil, and can be ground up to make flour.
Surrounding the short main stem of the hermit bud are flexible stems that help support the large inflorescence. These flexible stems are highly evolved and have a strong growth response to gravity, called gravitropism, and to touch, called thigmotropism. As the bud enlarges and gets heavier the stem expands outward like giant legs to support the increased weight. When an object or person stands close to a stem it will also grow towards the object and coil around it like a tendril, that makes hermit bud is weedy on Pandora. The Na'vi are careful to move quickly when harvesting seeds to avoid being caught in the web of stems. The plant grows incredibly quickly.
