Cicely Mary Barker's 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!

Candytuft
(Iberis)

The genus Iberis consists of about 50 species of annuals, perennials and evergreen subshrubs. They are excellent for rock gardens, bedding and borders. Candytuft is a fast-hardy, fast-growing annual with lance shaped green leaves. It reaches a height of about 12 inches with a spread of about 6 inches. It produces large racemes of small, fragrant, pink or white flowers in early Spring and Summer. The Hyacinth-flowered Series are sometimes used as cut flowers.

(Iberis umbellata) Native to the Mediterranean, this up-right bushy annual has flattish heads of small, mauve, lilac, pink, purple, carmine or white flowers that are produced in late spring or summer. This variety grows to a height of 6-12 inches with a spread of 8 inches. It is frost hardy and is a useful cut flower.

The Fairy Series has flowers in shades of pink, red, purple or which appear in Spring. Bushes in this series grow to a height and spread of 8 inches. Lightly trim after flowering.
