Thanks for the video Luis (I would like to grow cambucí!);
I went out and took some photos to the campomanesia lineatifolia seedlings, they sprouted on may, and now 7 month later they are like this:
I had some problems with dry conditions into the house in winter (you can see the damaged leaves still on them), so when I puted them into minigreenhouses they got better and better, then took them out in spring and now are taking some sun when the summer is about to begin... but the most part of the day are in shade.
They say maybe this is the tastier of campomanesias, in Colombia they know it.

They tend to tangle when just germinate: the tangled generally do not survive ... if I had known, would have unraveled.
