This is the father. I don't know the name of this one, but I've had it forever. I also don't believe it's hybridized because when I successfully selfed it, the babies that bloomed were exactly like it, no variations whatsoever.
Year after year I fertilized the crossed seedling and I was starting to think it was taking after its mother's dislike for blooming. All it did was make offsets. Finally this spring, it has sent up a flower stalk.
I thought the whole thing was going to be pink like the mom and you'd have to squint to see dad's stripes but this is interesting. I don't hate it but it looks generic, I'd say. At least it's a strong flower in appearance.
