I might have some Madagascar Jewel Seeds (Euphorbia leuconeura).
Although not a CP, this unusual and endangered plant is very easy to grow, and can live for over 20 years.
It has nice small white flowers, which self pollinate.
The plant SHOOTS it's seeds up to three meters away from the mother plants.
Madagascar Jewel can be grown in the same conditions as lowland Nepenthes, and can also grow as a houseplant.
I grow mine both in a terrarium, and on my outside porch.
I'm willing to trade for CP seeds, if anyone is interested.
Seeds will be freshly collected, especially for every shipment.
