A friend in Denmark is looking for seed of 'Luteosulcata', apparently it has flowered in Europe but I've heard of no offerings? The P. arcana here has not flowered and once it does I doubt it will be replanted as it has frozen to the ground inland at -20c the past 2 years.
I'd like to buy or trade for some Fargesia seed if anyone has had an aberrant flowering....seems someone mentioned that.
