On our recent holiday I saw Jade vine (Strongylodon macrobotrys) growing over a trellis at Flecker Botanical Gardens in Cairns. Because it is winter this vine would not have been at the peak of flowering but it was still spectacular.
The flower clusters can be over a metre long and are the most beautiful aquamarine colour. It is a truly spectacular vine. I’ve thought about growing this vine for a while now but have hesitated for two reasons. First, I may not be able to even source it in Brisbane and second, if I can, I'm not sure if it will survive our Winter.
They are native to the Phillipines (so I've been told) and I’ve read they will not tolerate frost or temperatures below 15 degrees C. But then I’ve also read elsewhere that people have successfully grown them in cooler areas. One person said they will tolerate winter as long as they aren’t too wet which sounds reasonable. I think I should try – It would be worth it.
