This is whiter than the other I posted a few days ago. Also its perfume is somewhat different, but stunning. It is some sort of herbal aroma (hard, if not impossible, to describe perfumes, ha?) that keeps your nose glued to the flowers, so wonderful it is!

For comparison purposes, I put side by side the two flowers. Both photos were taken three days after they were open in each case, as a way of preserving any possible value for the comparison.
