The Hulthemia Line

The Hulthemia blotch has fascinated many of us ever since Harkness and Cocker released their first hybrids.  In this post, I wanted to highlight something else that I am seeing in the Hulthemia hybrids - it is the Hulthemia line.

In several of the newer seedlings, I am seeing what appears to be an alternate representation of the blotch into what looks more like a line than a blotch.  Some of the seedlings are still showing a blotch at the base of their petals, however, others are just exhibiting a darker line down the center of their petals without any other evidence of the blotch.

I suspect that this line, through subsequent generations of selective breeding, can be darkened and emphasized.  Do you think that it is worth pursuing?!
