excellent! looks almost like a giant Lady Isabel!

I guess the petal length is probably to be expected...I read somewhere that things like flower dimensions are usually predicted with the geometric mean and not the arithmetic mean. i.e. if you cross a stonei with 5 inch petals with a 24-inch sanderianum, the geometric mean is the square root of 5 times 24, which roughly comes out to 11 inches (as perhaps the "average" sander's pride). if you cross that to a nice roths with 6 inch petals, the geometric mean would be the square root of 66, roughly 8 inches.

everyone always wants the outliers though! (and only those that shade towards LARGE flower parts)
