New Zealand has both the world’s tallest species of Fuchsia, Fuchsia excorticata (which can exceed heights of 12m (40 ft.)) and some of the world’s smallest species, like Fuchsia procumbens. Although the naturally-occurring hybrid Fuchsia × colensoi is considered to have the tall Fuchsia excorticata as one of its parents, individuals rarely exceed 3m (10 ft.).
The other parent species is thought to be scrambling fuchsia, Fuchsia perscandens–and indeed, Fuchsia × colensoi can be somewhat leggy in habit. This may explain the difficulty I am having in finding a photograph of a mature entire plant online.
The range of Fuchsia × colensoi does not always overlap with its parent species. For example, it occurs on New Zealand’s Stewart Island, where Fuchsia perscandens is absent. At some sites, it seems to form a hybrid swarm with its parent species, backcrossing and interbreeding such that a wide range of morphological variation can be found.
NZFlora has additional photographs (but none of the entire plant!): Fuchsia × colensoi.
