Alyssum Utriculatum

A native of the Levant, and cultivated by Mr. Miller in the year 1739.
Is a hardy and beautiful perennial, flowering from April to June, at which time it begins to form its curiously inflated pods.
Like the Alyssum deltoideum, it is well adapted to the decorating of walls, or rock work, and is readily propagated either by seeds or slips.
