Fine Line Improved is a unique update that has green, lush, and full foliage from tip to toe. It has bright yellow foliage in the fall. Dense branching provides good coverage for a space-saving hedge and gives it even more presence as a specimen. Like the original, it sets far fewer fruits than weedy buckthorns, and among the fruits that do develop, only a very low percentage are capable of germination. It is drought tolerant once established and is deer resistant.

  • 5-7 feet tall and 2-3 feet wide at maturity
  • Grow in zones 2-7
  • Plant in part to full sun (4+ hours daily)

Care: No pruning is usually required but may be pruned in late fall to remove dead or broken branches. Fertilize every spring with Proven Winners Continuous Release Plant Food.

    Fine Line Buckthorn doing great!

    A friend with inside connections to someone in the nursery biz has two buckthorns that have now almost reached the eaves of his home — spectacular! I looked for some in my local nurseries and couldn’t find any. Only one local nursery could ship 1 quart pots. Proven Winners offered 1 gallon size. I bought 4 of them. They arrived within 3 days of ordering. I planted one, then had to wait while we went through 3 days of blistering heat and humidity. The other 3 are planted now and all are doing very well. I’m going to have to wait a while before they reach over my head, but that’s what makes gardening such a hopeful hobby.

    great purchase

    when the plants arrived, the bottom of thr boxes had deteriorated due to dhe water leaking from the bag containg the root ball. the plants came in very good shape. put them in the ground within an hour or so. very lovly shrubs. i have admired these for a couple of years , now have them. i have found proven winners to be an excellent source for my plants. i try to purchase only proven winners plants when available . wish the local sellers had a bigger variety.
