Calandrinia grandiflora. - Great-flowering. - This is a half-hardy annual; grows two feet high ; blooms from June to October. It is a fine plant for growing in masses. When the fine, rosy lilac flowers of this very beautiful plant are fully expanded, being produced in vast profusion, and continuing for so long time in bloom, they make a pleasing appearance, and never fail to give ample satisfaction. To have it in its greatest perfection, the seed should be planted in pots, and placed in a hot-bed early in the spring. In June the plants should be turned into the ground. The soil should be a rich sandy loam.
Calandrinia discolor is in habit very much like the other; the foliage is purple on the under side; it requires the same treatment.
