Our red rose seems to have black around the edges of the blooms. It hasn't been that hot yet. What would cause this?

If the temps have dipped down pretty low at night at any time, it could be a bit of frost burn on the petal edges. Also, some of the darker red roses will at times have nearly black edges on their buds. However, if they are a bit crispy, as well as being black, it is either frost or wind burn since the heat is not an issue. It could also be a fungus, but most likely it is not that or the entire bud would have problems.
