الخلاف ضيق الأوراق أو الزيزفون السوري أو الزيتون الروسي أو الزيتونية نوع من الشجيرات أو الأشجار من جنس الخلاف من الفصيلة الخلافية. يعرف في بلاد الشام بالزيزفون، وهذا خطأ شائع لأنه يختلف جذرياً عن الزيزفون.

يكون ارتفاع الشجرة من 5-8 أمتار. أوراقها موبّرة رمحية متطاولة طولها من 2 إلى 6 سم سطحها العلوي فضي والسفلي رمادي، وهذا اللون من أهم ما يميز الشجرة. النورات صغيرة متجمعة في إبط الأوراق لها رائحة زكية جداً يفوح عبيرها في نيسان على مسافةٍ بعيدةٍ جداً. الثمرة فضية تشبه ثمرة الزيتون.

Russian olive is a large deciduous shrub or small tree that's remarkably hardy and beautiful but known to be invasive. It is native to southern Europe, Russia, central Asia and parts of China where it inhabits coastal regions, lakeshores, dry river beds and mountainous areas. It has also become naturalized throughout much of North America. In addition to its graceful habit and silvery leaves it is valued for its edible fruit, quality timber and fast-growing nature.

The narrow, lance-shaped leaves of Russian olive are green above and silvery, gray-green below. Its brown, scaly, often thorny branches are covered with exfoliating bark that adds winter interest. Silvery white, strongly fragrant flowers with yellow centers appear in late spring or early summer and are followed by edible, olive-like fruit.

This resilient tree is very tolerant of most growing conditions from dry to moist and sunny to shady. It is salt and drought tolerant and commonly found along sandy, coastal lands. Russian olive is grown primarily for its foliage and fragrant flowers but also makes an ideal barrier, screen or hedge, if pruned to retain a shrubby habit. (info source: Learn2Grow.com)
