I love my FineLine Buckthorn

I love my FineLine Buckthorn. It arrived looking beautiful. I put it in the ground within a couple of days. It is doing well. It has some growing to do to match the 4 that I already have but I'm happy to have a complete matching set.

A complete matching set is such a satisfying thing to achieve in the garden. Fine Line is pretty consistent in its form and texture as it matures, so your new addition should blend right in with the others over a season or two. Thanks for planting with us, Kimberly. The Nature Hills Team

Lovely tree

Lovely tree. Planting this week after a few weeks on our deck

Fine Line Buckthorn settles in well when given a little time to acclimate before planting, so it sounds like yours is off to a good start. Once it goes in the ground, keep the watering consistent through the first season and you should see it take off. Thanks for sharing, Virginia.

The packaging of my plants was the best of any nursery I have ever ordered from

The packaging of my plants was the best of any nursery I have ever ordered from. Great service and great delivery time.

Hearing that the packaging stood out after ordering from multiple nurseries really means a lot to us. We put a lot of care into how Fine Line Buckthorn ships, since it can be a finicky traveler. We hope it settles in beautifully and fills out that distinctive feathery texture you see at maturity. Thanks for the kind words, Pamela.

Fine Line Buckthorn

I own 11 of these in my landscaping, they are amazing and grow really fast. They are not invasive and they are great for privacy. I have a row of six of them, in two years and they are almost the same height as my six-foot fence. The other five are older and stand around 8 feet in height, I would suggest these for any landscape to help balance out the back round. I purchased half of them from nature hills and I was concerned when I received a box of branches as I described them, I planted them right away and they took off so don't get discouraged.

'Fineline' is a great accent plant in the landscape and is absolutely not invasive. I am an arboretum curator and also a landscape designer and have never seen a "volunteer" plant in either the arboretum nor any of my landscapes. 'Fineline' provides a great texture accent, and fits nearly anywhere. I just don't want people to panic when they see the word "buckthorn."

Thank you so much for sharing your thoughtful and professional perspective on Fine Line® Buckthorn. We truly appreciate your insight as an arboretum curator and landscape designer—it brings valuable clarity for our community of gardeners and plant enthusiasts.

We’ll be sure to highlight expert feedback like yours to help educate others and ensure this wonderful accent plant receives the appreciation it deserves.

Good plant in zone 7

Although, I didn't purchase my Fineline Buckthorn from this vendor, I felt I should offer a review in its defense. This shrub/tree is not invasive at all. The seeds are minimal in number and have not germinated anywhere in our yard. We were careful to select only this variety to plant. After three years in the ground the plant is 6.5 feet tall, and approx. 22 inches wide. It provides a pleasing variety of texture in our landscape.

It’s also encouraging to learn from your perspective that the plant hasn’t shown any invasive tendencies in your yard, as feedback like yours helps other gardeners feel confident in their selections.

If you’re interested in helping this shrub thrive even more, shading recommendations, proper pruning tips, or soil preferences designed for your zone might be helpful. We’d be happy to guide you further if you ever need—just reach out!

Frequently Asked Questions

Do deer eat buckthorn?

  • Deer typically avoid buckthorn, including Fine Line® Buckthorn, making it a reliable choice for deer-prone areas. The plant's natural properties tend to deter browsing. If deer pressure is severe in your landscape, Fine Line® can serve as a low-maintenance vertical accent without needing protection.

What growing zones is Fine Line Buckthorn hardy in?

  • Fine Line® Buckthorn is hardy in USDA zones 2-7, making it one of the most cold-tolerant vertical accent plants available. This drought-resistant cultivar thrives in both full sun and partial sun conditions. Check availability for your zone at naturehills.com.

How tall does Fine Line Buckthorn grow at maturity?

  • Fine Line Buckthorn reaches 5-7 feet tall and only 2-3 feet wide at maturity. This narrow, columnar growth habit makes it perfect for tight spaces where you need vertical interest. Plant it where you want a living screen or architectural accent without taking up much ground space.

Will Fine Line Buckthorn grow in shade?

  • Fine Line Buckthorn performs best in sun to part sun conditions and is not recommended for full shade. While it's adaptable to various light conditions, insufficient sunlight will result in poor growth and a less dense, attractive form. Plant in locations receiving at least 4-6 hours of direct sunlight daily for optimal performance.

Is Fine Line Buckthorn drought tolerant?

  • Yes, Fine Line Buckthorn is drought tolerant once established. This hardy cultivar thrives in both full sun and partial sun conditions with minimal water needs. Plant it in well-draining soil and water regularly the first year, then enjoy its low-maintenance nature available at naturehills.com.

What size plant ships when I order Fine Line Buckthorn?

  • Fine Line Buckthorn typically ships as a 1-2 year old plant in a container, ready to establish quickly in your landscape. The exact size varies by season and availability, but expect a well-rooted specimen that will begin showing its characteristic narrow, upright form immediately. Plant in spring or fall for best establishment.

Does Fine Line Buckthorn require pruning?

  • Fine Line Buckthorn maintains its narrow, upright form naturally with minimal pruning needed. Its strongly vertical habit and architectural structure develop on their own. Light pruning in late winter can help maintain shape if desired.

What soil conditions does Fine Line Buckthorn prefer?

  • Fine Line Buckthorn adapts to a wide range of soil conditions and is quite drought-tolerant once established. It thrives in both full sun and partial sun locations. For best results, plant in well-draining soil and water regularly the first year to establish strong roots.

Is Fine Line Buckthorn invasive?

  • Fine Line® Buckthorn is a sterile cultivar with only 2% viable seeds, making it much less invasive than standard buckthorn species. However, some states still restrict shipping due to the genus's invasive history. Check your local regulations before purchasing, as availability varies by location.
