|Some sources list fuchsia magellanica as hardy to Zone 5. Is it really? Is there a way to find out for sure without possibly killing the plant?! I've seen it growing outdoors on the Isle of Iona, much further north but in the warm current -- but also blasted by sea winds. Authoritative references would be appreciated. Thanks.|
|Fuchsia Magellanica is hardy in zones 3-10. Plant in well-drained, moist, fertile soil in full sun to light shade. Space plants 24-36" apart. Pinch plants when young to achieve a bushy shape. Prune as necessary in spring, removing any dead wood and cutting back last year's growth to 2-3 buds. This hardy fuchsia grows up to 6' tall and wide and flowers all summer, beginning in late May. You can read more about this plant in Hortus III, available at most libraries.
Best wishes with your garden!
