Is N. cassata a species? I love your flowers. Hard for me to believe somewhere in the US that garden is blooming its head off while I watch the snow fall. But really nice to see. I am getting excited about giving spring bulbs another try. And am hoping what I dug up and redistributed last fall does something this spring. I scattered bone meal on all the plantings and even mixed some into the soil before planting to try to give them a good start.
