It's beautiful all season long. The color turns golden-yellow in the fall in years when the cooler weather comes on slowly.

Fine Line provides a high-end, designer look, but it is so hardy and easy to grow. This drought-tolerant plant even does well in either sun or part sun conditions. It has few insect or disease problems. And deer tend to leave it alone.

Please note, the Buckthorn genus has proven invasive in certain areas. The improved Fine Line cultivar does produce some inconspicuous flowers in early spring. But, it produces very few fruits and of those, only 2% of the seeds are viable.

However, we may not be able to ship into your state if it performs too well. Birds do love to eat the small, dark fruit and it can spread in certain areas.

Nature Hills uses Plant Sentry™, an online platform that blocks shipments of all invasive plants in vulnerable areas. We comply with every United States federal and state regulation for proper shipping of plant material. Thank you for shopping with us and supporting the needs of your local ecosystem!

Fine Line is an improved Buckthorn that features a wonderful texture and a handsome columnar shape. It's tough, adaptable and gorgeous, easily adding height to landscaping without taking up a lot of horizontal space.

#ProPlantTips for Care

Plant your Fine Line Buckthorn in partial sun or full sun for best results. They require well-drained soil, so plant in a raised bed or container if you have heavy soil that holds water.

Give a moderate amount of water on a regular basis the first season. Once their root system is established in your landscape, they become drought tolerant.

Very little pruning is needed, but you can snip any errant branch any time of year. All plants do well with good air circulation.

This special plant gets rave reviews but must be selected with a little care. Let our system determine if this beautiful plant will work for you. Enjoy!
