Holy cow, 11 blooms! That must be a record. The fragrance of only one bloom fills an entire room, I cannot imagine what 11 would do.
I’ve had the great grandmother of the present plant, she was a cutting from a hundred year-old plant when I received it as a gift. I’ve made babies and given them away to a few people, who have also enjoyed not only the fragrance but the beauty, as well. And I always keep a back-up plant, just in case.
