This graceful Amaryllis has the colour of cherry blossoms, so the grower must have gotten his inspiration for her name from her colour. According to the rules of the names of flower bulbs (yes, there are rules: quite a lot of them, actually), you cannot name a flower after another flower: this might cause misunderstandings for the customers. Those rules didn’t exist back in the day, so it must be super confusing that there are no actual apples involved in the growing of Amaryllis Apple Blossom. What would we ever do without the rules.
But the Amaryllis herself doesn’t seem to care about any of it: she is just as pretty as cherry blossoms.
