What's the symbolism here?

Curious, very curious

Beginning the mystery of the black pansy.

I prefer starting from seeds rather than buying already blossoming plants off the rack at the supermarket, so these just showed up in the past week after a start indoors and more than a month outdoors.

Sure enough the black pansies came up and looking ever so cool. A friend had asked why I bought black pansies and I told her i would take a bouquet of them to give to someone I don't like, a sinister warning, but with no real threat behind it, and I didn't really have anyone in mind, except one and that one is too easy.

Now I think they have more of a use as something of a muse. But the pansies, at least one, added an unexpected twist.

What could it possibly mean if a black pansy grows with holes at the dead center of three of the four petals? What does the black symbolize? That's a fairly common theme, dark, black, night, generally evil. But what abut the holes? And further, why only three? What is the symbolism there, and is it in the three with holes or the one without?

It's enough to get the mind percolating.
