A plant in our garden normally gives us pink flowers. This year, however, the flowers are black. Any ideas?

I would need to know the kind of flower to make a really good educated guess, but I can give you the general reasons.
First, if it is a plant that reseeds itself, it may have been pollinated by a black variety and you are seeing the offspring from that.
You may also have a sport, which is a plant who has a deformity essentially in its genetic code. These are rare though.
You may also have a plant that was a hybrid and it is reverting to its original form. This happens again on plants that reseed themselves.
