The jacaranda is a tree originally from Mexico. It is deciduous, and is covered in purple flowers in spring. They survive well in areas with long, hot summers. Jacarandas are frost sensitive when they are young, but frost hardy when they are older.
Jack Russells are small dogs that are mainly white, with patches of brown or black. They might have smooth or rough coats. They were originally bred for hunting foxes. They are intelligent, energetic, fearless and vocal. If they are left alone or not exercised enough, they can get bored and destructive. They do not make good indoor dogs.
A jackal is a small to medium sized close relative of the dog. They are found in Africa, Asia and some parts of Europe. Jackals normally live together in pairs, although they will sometimes form small packs to hunt. They hunt small to medium animals, and will eat dead animals they find. Like household dogs they will also eat fruit and other plants as well as meat.
