Now I'm even more confused about the leaf pattern. Here is what Sybil from Paradise says about the Violette on her blog:
** Violette - The true Violette introduced by Mike McConkey at Edible Landscaping. This variety has a thin, long-lobed leaf and is very distinct. If you have a long warm fall season in your area, these fruits slowly ripen to a perfect, wrinkled heaven of sweetness. Unmistakable! This tree was cut severely back after storm damage and so there will be fewer cuttings of this than the others so put your request for this one in early! (FYI, yes, this is the Violette de Bourdeaux, according to Mike McConkey.)
I bought the Violette from her almost 10 years ago. I still have 2 originals from her. As soon as they leaf out fully I will post pictures of the leaves.
Here is another picture from a few years back. Notice different leaf patterns.
