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.

- use fresh seed as it loses viability fast
- sow in sowing substrate
- 25-30 °C
- take stem cuttings with at least 1 node
- notch the bottom of the cutting in order to promote callus formation
- plant in potting soil with 50% perlite
- provide soil heating
- root formation occurs in about 6 weeks
- after rooting, the cuttings may be transplanted to a more nutritious substrate
- after 18 months, the plant has grown meters long
