The Distinguished Carpinus Betulus ‘Frans Fontaine’ HornbeamThe Carpinus betulus ‘Frans Fontaine’ hornbeam is one of the most popular and distinguished cultivars of the European hornbeam tree With its upright, narrow form and lush green foliage, it makes an excellent vertical accent in landscapes and gardens In this article, we’ll explore the origins, notable attributes, landscape uses, and care for this exceptional hornbeam cultivar.

Origins of an Outstanding Cultivar
The ‘Frans Fontaine’ hornbeam arose in the 1930s as a chance seedling at the famous nursery of Frans Fontaine in Boskoop, Netherlands. It was named after the nursery’s owner and proved superior to the hornbeam species with its uniform narrow habit and urban tolerance. Other Carpinus betulus cultivars like ‘Fastigiata’ and ‘Pyramidalis’ share the columnar form but lack the consistency and vigor of ‘Frans Fontaine’. As a result, ‘Frans Fontaine’ emerged as the premier hornbeam for modern landscapes.

Interesting Facts: Full-grown “Frans Fontaine” hornbeams are 30 to 40 feet tall and 15 to 20 feet wide. Their shape is narrowly pyramidal to columnar, and their branches are strongly upright. In the spring, the leaves are a bright green color, but by summer, they are a deep green color. As fall comes around, the leaves turn from golden yellow to orange-red, and they stay on the trees all winter before falling off. “Frans Fontaine” can grow in USDA zone 4 and does well in a wide range of soils.

Perfect for Landscape Designs
With its tightly upright habit, ‘Frans Fontaine’ hornbeam serves as an exclamation point in gardens. It makes an excellent vertical accent along walkways, entries, and corners. Lines of ‘Frans Fontaine’ form striking alleyways and living screens. In formal designs, it lends structure pruned into hedges or topiaries. Its compact size also suits urban sites like sidewalk cutouts and small backyards.

Easy CareOnce established, ‘Frans Fontaine’ thrives on minimal care. It prefers full sun but accepts partial shade. When pruned once in a while in early summer, it keeps its columnar shape. Like other hornbeams, “Frans Fontaine” is very resistant to pests and diseases.

An Ideal Urban Tree
For small spaces seeking a refined vertical accent, few trees compare to the Carpinus betulus ‘Frans Fontaine’ hornbeam. This distinguished cultivar combines strong architecture, four-season appeal, adaptability to urban sites, and elegant proportions. The ‘Frans Fontaine’ hornbeam richly deserves its reputation as the premier hornbeam tree for modern landscapes.

While “Frans Fontaine” is still the most popular hornbeam cultivar, here are some other Carpinus betulus cultivars that you might want to think about:

• Carpinus betulus “Fastigiata” is a vase-shaped hornbeam that grows straight up and is 40 feet tall and 20 feet wide. Offers a slightly broader form than ‘Frans Fontaine’.

• Carpinus betulus ‘Columnaris’ – Very narrow in growth, forming a dense columnar habit. Grows slower than ‘Frans Fontaine’, maturing at 25 feet tall and just 10 feet wide.

• Carpinus betulus ‘Monumentalis’ – Develops a narrowly upright oval form, a bit less columnar than ‘Frans Fontaine’. Grows 30-40 feet high and 15 feet wide.

• Carpinus betulus ‘Bornyensis’ – A dwarf hornbeam that matures at just 15 feet tall and 10 feet wide. Offers a globular, compact shape.

While these other Carpinus betulus cultivars have merits, ‘Frans Fontaine’ remains the most elegant and distinguished option for its uniform narrow habit, fast growth, and reliability in diverse landscapes. It sets the standard for hornbeams in modern garden design.
