|Homeworld||Unknown (Possibly Aether)|
Blueroot Trees are a species of tree-like flora which is commonly found on planets that possess a desert region. This has blurred which might be their homeworld, although it is speculated that it may have originated on the Space Pirate's. They are considered quite an attractive and elegant specimen, although this underlays the fact that their leaves are highly toxic. Few species are capable of ingesting the leaves and surviving the encounter: many of them (including the aforementioned Space Pirates) consider the deadly Blueroot leaf to be a delicacy.
