Answer: I believe you are describing Koelreuteria paniculata, Panicled Goldenrain Tree or Varnish Tree. According to Michael Dirr's Manual of Woody Landscape Plants, this tree is easy to start from seed. He suggests soaking the cleaned seed in concentrated sulfuric acid for 60 minutes to counter the impermeable seed coat and then placing it in moist stratification at 41 degrees for three months. At home, I think I would gently rub the seeds with a bit of sand paper, then place them in barely moist medium such as milled sphagnum peat moss or vermiculite and wrap that in a plastic bag and put it in the refrigerator for about three months. Then plant as you would any other seeds.
