The flowers are both delicate and coarse at the same time.
Yellow buckeye (A. flava) is a smallish tree from the western part of the state that doesn't really grow around here naturally, but there is a nice specimen in Colonial Williamsburg. By the way, CW is a great place to gather all kinds of seeds...I hope they don't mind!
You could say the flowers are 'interesting' but there's no way around it...the blooms just aren't as pretty as red buckeye.
So I collected bottlebrush seeds a couple of weeks ago, and yellow buckeye seeds within the last couple of days. The yellow buckeye seeds are quite a bit darker than the bottlebrush seeds.
Last year, I planted seeds outside in pots but none of them came up. I read somewhere that planting them in moist sand was a good way to go, so I tried that this time. I'm also keeping them in the garage (to keep critters away). I've had excellent results, with 100% germination for the bottlebrush seeds. I just planted the yellow buckeyes today so we'll see on those.
This afternoon I moved the bottlebrush seeds to a soil mix to sit for the winter. Here's a seed that I just pulled from the sand about 2 weeks after going in. The roots are emerging from cracks in the sides of the seeds. I'd recommend planting them with the 'eye' of the seed up, though it probably doesn't matter too much.
