While the association of specific flowers with birth months has been around for centuries, the concept of a "Birth Flower Family" as a distinct practice or tradition with a documented history isn't clear-cut
The tradition of assigning specific flowers to each month appears to have originated in Victorian England during the 19th century. Victorians used flowers to express emotions and sentiments, and associating a flower with each month offered a convenient and symbolic way to convey a message.
The specific meanings and associations attributed to birth flowers may vary depending on the source and historical context.
