I am often asked to "send your prettiest flower arrangement." There is no such thing as the "prettiest flower arrangement." Rather, beauty is in the eye of the beholder. Everyone (and I do mean EVERYONE) has different likes and dislikes when it comes to flowers. So if you know and send the recipient's favorite flower or plant, s/he more likely than not will way this is the most beautiful thing s/he has ever seen.
This concept recently came up when a sender couldn't decide whether she send orchid plants, or a flower arrangement with hydrangrea or peonies. The sender was sure the recipient liked all three. So I said let me put all three in the same container. There are three single stem phalaenopsis orchid plants surrounding a small vase that has hydrangea and peonies. The recipient loved it. Do you?
