Strongylodon macrobotrys flower

Strongylodon macrobotrys or Jade Vine is a vine with amazing blue green flowers on long hanging racemes.

In its habitat it is threatened by exploitation of the rainforest.

In nature pollination is done by bats and it took until 1995 before they succeeded in Kew gardens to mimic this process and get fruit.

Although this vine comes from the rainforest, it seems to tolerate lower temperatures and humidity. The Botanic Garden of Meise has plants growing in a slightly cooler greenhouse with less humidity.
