WHAT’S IN A NATIVAR?

BY CAROL BECKER

And what isn’t? Designers and pollinators are finding out.

FROM THE JULY 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Common buttonbush (Cephalanthus occidentalis) is a medium-sized shrub that is appealing in sunny areas of the landscape because of its glossy green leaves; unusual fragrant, round, spiky flowers; and rust-red fall color. It’s especially useful in wet areas and rain gardens where it absorbs excess water and even tolerates standing water. Hummingbirds and butterflies favor the plant for its nectar, and 24 species of birds seek it out for its small, round nuts that persist into winter. This native of the Midwest and East Coast is easily grown and little bothered by pests in the garden. Yet it is not commonly used in built landscapes. Although everything else about this shrub is right, its growth pattern and size are not. The straight species can be quite large at 12 feet high or more, and it has an annoying habit of sending branches in all directions, so it looks willy-nilly rather quickly if it’s not pruned regularly and often.

But here come Sputnik, Sugar Shack, and Fiber Optics, cultivars of buttonbush that represent a tamed C. occidentalis. Cultivars are plants produced by selective breeding or vegetative propagation to achieve better traits for the landscape. Fiber Optics is a species mutation discovered by an inventory employee in the bare-root fields of Bailey Nurseries, says the company’s public relations and communications specialist, Ryan McEnaney. Bailey trialed the plant, a process that takes several years, and brought it to market in 2017. It has a reliably smaller size at five to six feet high and a branching habit that keeps it compact and rounded, while retaining all the desired features of the straight species.

The Fiber Optics buttonbush is what is known as a nativar. The term is not scientific but has value to the industry in (more…)
