“Pomona’s themes are rest, pleasure, and nature. Her symbols are all flowers and gardens. A Roman Goddess of orchards and gardens, Pomona is symbolized by all gardening implements. Pomona’s consort was Vertumnus, who likewise presided over gardens. Together they embody the fruitful earth, from which we gather physical and spiritual sustenance. First fruits are traditionally offered to them in gratitude.
Public games in ancient Rome were dedicated to taking a much needed rest from toil and war. Ludi was a segment of the festival that celebrated the beauty of flowers before people returned to the fields and their labors. So, wear a floral- or leafy print outfit today and visit a greenhouse or an arboretum. Take time out to literally smell the flowers and thank Pomona for the simple pleasure this provides.
Make yourself a Pomona oil to dab on anytime you want to better appreciate nature or cultivate some diversion from your normal routine. Prepare this from the petals of as many different flowers as you can find, gathered early in the day. Steep the petals in warm oil until they turn translucent, then strain. Repeat and add essential oils (fruity ones for Pomona are ideal) to accentuate the aroma and energy you’ve created.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Pomona was a Goddess of fruitful abundance in ancient Roman religion and myth. Her name comes from the Latin word pomum, “fruit,” specifically orchard fruit. (“Pomme” is the French word for “apple”.) She was said to be a wood nymph and a part of the Numia, guardian spirits who watch over people, places, or homes. She scorned the love of the woodland gods Silvanus and Picus, but married Vertumnus after he tricked Her, disguised as an old woman. She and Vertumnus shared a festival held on August 13th. Her high priest was called the flamen Pomonalis. The pruning knife was Her attribute. There is a grove that is sacred to Her called the Pomonal, located not far from Ostia, the ancient port of Rome.
Pomona was the Goddess of fruit trees, garden, and orchards. Unlike many other Roman Goddesses and gods, She does not have a Greek counterpart. She watches over and protects fruit trees and cares for their cultivation. She was not actually associated with the harvest of fruits itself, but with the flourishing of the fruit trees.” 
“Despite her being a rather obscure deity, Pomona’s likeness appears many times in classical art, including paintings by Rubens and Rembrandt, and a number of sculptures. She is typically represented as a lovely maiden with an armful of fruit and a pruning knife in one hand.
In J.K. Rowling’s Harry Potter series, Professor Sprout, the teacher of Herbology — the study of magical plants — is named Pomona.”
