The 'Flower of the Month' for May is the Lily, specifically, depending on the source, the 'Lily of The Valley'. It is a small flower that blooms in clusters and is white. When I think of lilies, ones like the Royal Heiress come to mind.
There are hundreds of different true lilies, they are a perennial plants, and have numerous meanings...royalty and regal bearing, motherhood and fertility, purity and the beauty of youth, passion and drive, and renewal and rebirth. This Royal Heiress blooms every year in a Lily Garden a few miles from where I live.
Yes, Rose, 'Friends are Forever', and so it seems so are Lilies!
