Fine Line Buckthorn (non invasive)

Fine Line Buckthorn ‘ Ron Williams’ – Rhamus frangula

Fine Line Buckthorn 'Ron Williams' - Rhamus frangula

A Versatile and Non-invasive Shrub for your Garden

Fine Line Buckthorn, also known as Rhamnus frangula ‘Ron Williams’, is a unique cultivar of the European Buckthorn shrub. This adaptable plant boasts a fascinating heritage, being a hybrid of the cultivars R. frangula ‘Aspleniifolia’ and ‘Columnaris’. It combines the fern-like foliage of ‘Aspleniifolia’ with the slender, upright form of ‘Columnaris’, creating a visual masterpiece for your garden. While native to regions of Europe and western Asia, it has become widely cultivated across North America for its ornamental appeal, ease of care, and non-invasive nature.

Unlike other Buckthorn varieties known for their aggressive spread, Fine Line Buckthorn produces very few fruit, and among those, only a tiny fraction (2%) are even viable. This makes it a responsible choice for gardeners concerned about invasive plants and ecological balance.

When paired with other plants, Fine Line Buckthorn creates stunning visual contrasts. Consider low-growing perennials like lavender or sedum that complement its airy texture. For vibrant color combinations, plant it alongside flowering shrubs like potentilla or hydrangea. Taller perennials like Russian sage or ornamental grasses can also add depth and interest to the planting.
