Hey are there any saints who are associated with a certain color or a flower? Especially roses?
The biggest one of all, St. Mary is called Our Lady of the Roses! There's also St. Therese of Lisieux who is referred to as The Little Flower.
When you smell roses and there is no obvious source for it, it means saints are near.
I would also read up on Odor of sanctity. It's a really cool.
I forgot my favorite Saint Bernadette has an uncorrupted body and when they performed an autopsy on her apparently her insides smelled like roses.
Saint Dymphna is associated with lilies.
