Please help me to identify this plant. I grew it from seeds. Seeds brought my friend from Spain. Perhaps it is tree (grows very quickly). The plant has grown to 1 meter per season. Maybe it is from Acacia Family or Koelreuteria paniculata. Thank you

Koelreuteria sp.

I agree, it reminds me of seedlings of Golden Rain Tree (Koelreuteria elegans) that used to pop up in my garden.

Thank you very much. I am very glad that it is Koelreuteria.This plant does not grow in Belarus. I have to provide enough winter protection (Zone 5a). I will see the result in spring
