Ziziphus jujuba , we call it žižola in Slovene, is not a well known fruit in my country. It grows at the coastal region and can be only seldom found at food markets elsewhere. No doubt I was happy getting the opportunity to take some photos of a nice Ziziphus jujuba tree !
Fascinating enough, the species was domesticated already 11000 years ago, in South Asia. Yet the plant has got its proper scientific name just recently!
In 2006, a proposal was made to suppress the name Ziziphus zizyphus in favor of Ziziphus jujuba, and this proposal was accepted in 2011. Ziziphus jujuba is thus the correct scientific name for this species. from: http://en.wikipedia.org/wiki/Jujube
