Clematis Avalanche was originally a native to New Zealand. One of the hardiest species of Clematis, the plant was suited to drier alpine regions.

 

Predominantly cultivated in gardens, its native population was already sparse. 

 

With wetter conditions severely impacting New Zealand's biosphere towards the end of the 21st Century, all species of clematis native to the Islands died out by 2105. 

 

The last known wild specimen of Avalanche died in 2090.
