Iberis, from the country called Iberia, now Spain. Most of the species grow in such countries. They are generally pretty plants, and some of them cultivated in gardens as hardy annuals, under the name of Candy-Tuft, - a name which was originally applied to the I. umbellata only, which was first discovered in Candia.
I. umbellata has umbels of purple flowers, in June and July.
I. amara, or bitter, has white flowers, in umbels, at the same time. Both are hardy annuals, of no little beauty, (the last from England,) and worthy of cultivation. The seed should be sown early in April; height about one foot.
I. coronaria. - Rocket Candy-Tuft. - This hardy annual is of considerable beauty, being very showy, and a pure white. The clusters of racemes are numerous and very large, being three or four inches long. At a distance, the fine flowers very much resemble the Double White Rocket. It blooms for several months during the summer. It well deserves a place in every flower-garden.
All the species and varieties of the Candy-Tuft are very hardy, and easy to cultivate. The fall-sown seeds flower early, those sown in April, from July to September; and some of the species until the frost in October. There is a variety, called the New Crimson, that is not crimson, but a deep, rich purple. All the varieties look best in beds, or masses.
