Proven Winners® FINE LINE ® Buckthorn Fern-leaf 
Rhamnus frangula 'Ron Williams' USPP 14,791
 
Narrow, upright form. A very versatile landscape plant, Fine Line® rhamnus combines the feathery foliage of 'Asplenifolia' with the narrow upright habit of 'Columnaris.' This cultivar produces very few fruit, and even fewer actual seeds. Germination has been shown to be extremely low, and as such, many states that have banned rhamnus from the trade have made an exemption for this fine, in-demand selection. Now, Frangula alnus is considered the correct scientific name.
