I got the seeds of this lovely tree and I decided to plant some (on october) and keep the rest to plant next spring. The seeds are so tiny, I planted them in a container and covered them then put them indoors at a south facing window, they germenate the next 7 days, some died out after transplanting and some (like this one) thrived. Hope it can hold it self to be a big tree. I heard that they grow very fast (1- 3m a year!). I am excited to see it grow and will keep you posted (Photos taken 05 January 2018):
1-3 Meters a year - now that's some growth spurt!! So by this time next year they'll be lovely saplings.
