På något sätt hamnade jag på den här intressanta sidan What's in a plant's name (handlar om ord och växter!)
och där hittade jag denna söta lilla dikt:

THE ROSE FAMILY
The rose is a rose,
And was always a rose.
But the theory now goes
That the apple's a rose,
And the pear is, and so's
The plum I suppose.
The dear only knows
What will next prove a rose.
You, of course, are a rose -
But were always a rose.
