Cephalanthus occidentalis Fiber Optics

The Cephalanthus occidentalis Fiber Optics is an improvement of the species, presenting a more compact habit and moderate growth, not exceeding 1.50 m in all directions. This bush is cultivated for its original and bright flowering with tiny narrow, cream-white flowers, gathered in perfect spheres, adorned with fine and prominent stamens. They release a pleasant fragrance and attract a large number of bees and butterflies. Bright red fruits, similar in appearance to arbutus, follow, standing out from its large, oval, dark green foliage, colouring the garden until winter. The seeds are adored by birds. It is a very robust bush that perfectly withstands freezing temperatures and is suitable for cool to wet soils, normal to heavy, even tolerating temporary flooding and partial shade. It blooms better in the sun and planting in limestone or dry soil should be avoided. It is an ornamental plant, suitable for enhancing pond banks or flower beds in not too dry soil, with other flowering perennials. 

Cephalanthus occidentalis belongs to the Rubiaceae family, just like Gardenia, coffee or quinine. This deciduous and very hardy bush is native to North America, specifically wet to marshy areas in Eastern Canada and the United States. Its distribution range extends to Mexico and Cuba where it often forms very dense groups. Its grey-brown bark cracks with age, exfoliating in thick flakes. Tolerating the shade well, Buttonbush are much more floriferous in the non-scorching sun.

The cultivar 'Fiber Optics', obtained in 2005 in the USA by breeder Jon Burns, is distinguished mainly by a much more compact habit and reduced growth. It quickly forms a very dense bush, producing numerous highly branched stems from its base. At maturity, the bush will reach approximately 1.50 m in all directions. The grey-brown branches bear deciduous leaves that bud late in spring, taking on coppery-red tones. They are leathery, 10 cm long, ovate, lanceolate, with shiny olive-green to dark green on the upper side before turning dark green, lighter underneath, with lighter veins giving the lamina a waffle-like appearance. The autumn foliage shows a beautiful golden yellow colour, sometimes tinged with coppery-red before falling. From August to September, depending on the climate, for approximately 8 weeks, the unusual flowering of this plant unfolds. At the tips of the branches of the year, a long branched petiole appears, each branch bearing a very dense globular flower head measuring approximately 3 cm in diameter. Each inflorescence or 'pom-pom' is composed of tiny tubular cream-white flowers with prominent yellow stamens resembling pinheads. This fragrant, nectar-bearing and honey-producing flowering attracts many pollinating insects. The fruit is a round, very bright red capsule, downy in appearance, measuring 2 cm in diameter, which remains on the branches until winter. The root system of Cephalanthus is superficial, making it sensitive to lack of water but easy to transplant.

Cephalanthus occidentalis 'Fiber Optics' is a beautiful bush that produces honey and has an ornamental appearance. It thrives in soils that retain moisture and in humid areas like marshes or waterlogged surroundings. This makes it a great addition to pond borders or for planting alongside other water-loving plants like Japanese irises, ligularias, astilbes, or filipendulas. However, it's not limited to these areas and can grow comfortably in any soil that's not excessively high in limestone and doesn't dry out. It's versatile enough to be integrated into a small flowering hedge or a low shrub bed alongside other plants like hedge honeysuckles, evergreen or deciduous barberries, flowering currants, dwarf lilacs, and dogwoods. Its compact size makes it perfect for container or pot cultivation, with regular watering and fertilising.
