Haha, My plant is recovering as well. I brought it over to my mother's place for Christmas a few years ago and she overwatered the plant so it has declined in size. It is recovering now and has not flowered in for 3 years.
I wondered about that a few years ago. I heard that the coerula form tend to produce a growth with leaf and flower. Sometimes walkeriana do form a new leave with the developing bud and it depends on your conditions.
