My Crown Flower has finally gotten buds. How long does it take for them to open? I keep expecting to see a flower but the buds just keep getting bigger. There's about 10 buds in each cluster and the biggest buds are almost an inch long. I'm hoping that they open before it has to go back in the greenhouse for the winter. Last year it had a couple buds at a much earlier stage and they dropped when I moved it. I'd really like to see this in bloom already. I was also wondering if it had a scent?
