The flowers of this plant, a native of Gibraltar, bear some resemblance to those of the Common Candy-Tuft, but when they blow in perfection, they are usually twice as large; hence they are highly ornamental in the green-house, which early in the Spring, the time of their coming forth, stands in need of some such shewy flowers.
This plant is easily raised from cuttings, and easily preserved; it may be kept through the Winter in a common hot-bed frame, and in mild Winters will stand abroad, especially if sheltered amongst rock-work; its greatest enemy is moisture in the Winter season, this often proves fatal to it, as indeed a long continued damp atmosphere does to many others; the Nurserymen about London complain of losing more plants the last mild Winter, from this cause, than they generally do from severe frosts. In a little green-house which I had in my late garden, Lambeth-Marsh, most of the plants became absolutely mouldy; in such seasons then, though in point of cold the plants may not require it, we must dissipate the superfluous moisture by a gentle heat.
