From what I knew it’s because you bought an even number, kept one (that’s the important part) and offered the (now odd) bouquet. When your flower had wilted, you knew you could offer another one.
That would make sense ! When i heard about it, it was florists advising to buy an even number from the start, so the meaning of it probably got lost somewhere, but i like the explanation.
It is also present in France, i heard about never making an even bouquet, and judging by the internet, it’s because it’s also meant for funerals.
