The Candytuft Fairy

Why am I “Candytuft”?
That I don’t know!
Maybe the fairies
First called me so;
Maybe the children,
Just for a joke;
(I’m in the gardens
Of most little folk).

Look at my clusters!
See how they grow:
Some pink or purple,
Some white as snow;
Petals uneven,
Big ones and small;
Not very tufty—
No candy at all!
