Hi,

first of all thanks a lot for your answer :)

Mmmh, seems that there are various Lucky Bean trees. I have three E. caffra, but they are completely different (nearly triangle-shaped and prickly leaflets and also prickly stems, leaves always consisting of three leaflets). At night, they fold their leaves together, like all other Leguminosae trees I have. My "Lucky Bean Tree" doesn't. But, while googling, I found a picture of "my" plant, unfortunately without scientific name.

Anyway, the hint "Lucky Bean Tree" is quite a good starting point. Will keep on googling.

Thanks!! Gaby
