Tabernaemontana Undulata, got any cultivation experience to share?

[ManicMongrel]

If you are growing this plant feel free to share your experiences!

Its an odd plant and from what I can understand from older threads, its rumored to have somewhat different pharmacological properties for leaves, stem and roots.

In my experience seeds from Tabernaemontana Undulata turned out to be eager to sprout and put out their first few sets of leaves, then the stem growth slows down but roots growth is fast and stable. They seem to like really moist, slightly sour soil with plenty of cavities from coarse compost.

I assume this plant is getting popular among collectors, it should be though. Its a remarkably tough plant, it tolerates dry air and sub-tropic temperatures far better than Psychotria Alba and other plants from the same climate zone.

It has some interesting defense properties, it seems to produce waxy excretions around new emerging leaf and stems in response to fungus gnats and other pests. It also produce small waxy taps on the underside of the leaves in response to stress.

It looks like leaf stems can be milked for latex on older plants, that could be a pretty useful way to get substrate for analysis.

When I get them into a new incubation chamber with proper growth conditions and grow-led fixtures I expect them to grow pretty fast.

One thing is very strange with these though, they fought off spider mites and gnat larva as soon as the temp and humidity was right. That sounds promising for terpene and alkaloid profiles.
