Rhamnus frangula Fine Line®
Fine Line Alder Buckthorn
RAM-nus frang-U-la, FRANG-gew-la
Native to (or naturalized in) Oregon:
- Broadleaf deciduous shrub, narrow columnar habit, to about 5-7 ft tall and 2-3 f wide (1.5-2.1 × 0.6-0.9 m). Freely branching. Narrow, linear undulate foliage which gives the plant a feathery appearance. Reportedly it produces few fruit and its seeds have low viability, hence non-invasive.
- Hardy to USDA Zone 3
- Very adaptable, best with well-drained soils. Pruning seldom needed. Can be used as a narrow hedge or accent specimen.
- Selected by Ronald Williams of Green Bay, Wisconsin. It originated from a chance cross-pollination in 1989 of the Rhamnus frangula ‘Columnaris’. US PP 14, 791.
