What Hybrids do you have the most trouble with?

[Ryumia]

I'm solely focused on getting two hybrids for my town. Those hybrids are: purple pansies and blue violets. And the one that I have the most trouble with is the blue violets. Sometimes I would get some and sometimes I wouldn't get any at all. My purple pansies that I have doesn't give me any trouble whatsoever and is able to grow lots of each other. I really want lots of blue violets. :T
