I planted seeds from 'Ryusen' and dozens germinated. I put 6 in individual pots, and one of them seems to show the characteristics of the mother-plant : horizontal growth, curved lines. I hope it survives ! All the others look "normal".
Looks like a winner there Alain, some staking in Spring would be my next move. I've always loved the cascading appearance of Ryusen.
I also have a few nice seedlings from the same cultivar that showing great promise. I think i will stalk a few and let the rest spread naturally.
2-1, you beat me ! ;-) There weren't many seeds on my Ryusen this year, and I sent them to... Poland. But if next year I can have a good crop, I'll keep some for myself ^_^
