How long does it take for a rose to turn black and decompose?

Question

Because I have a yellow rose in my room. I've had it just sitting there for almost 3 months now. Its dried out, but its still yellow and hasn't even wilted or anything. how long til it turns brown or black or whatever and decomposes?

Answer 1

it all depends, all flowers and plants are different in that respect, though I dont think it will ever decompose ( it may or may not lose its color ) since you took it out of its natural environment and preserved it like that, that is where potpourri comes from, people drying out flowers such as you did and putting them in baskets for their scents, they last forever.
