Thanks.
I measured when it bloomed - which brings up the question of how to measure. The width from point to point was 6 inches. However the petal itself was 4 and 1/4 inches deep. I assume across the bloom is the usual way it is done though.
It seems it is Lemon Something. I should just enjoy it when it blooms, which is the general idea I suppose.
Meanwhile, its baby has leaves and its own root system so I repotted them today.
