The Alternantheras, Amaranthuses, Iresines and Coleus Verschaffelti furnish high and warm colours; while Pyrethrum Parthenium aureum yields greenish-yellow; Thymus citriodorus aureus, yellowish; Mesembryanthemum cordifolium variegatum, creamy yellow; Centaureas and others, white; Lobelia Erinus, blue; and the succulent Echeverias and Sempervivums, glaucous rosettes, which last add much to the general effect.
Many of the pieces are distinguished by a peculiar creamy whiteness of glaze, suggesting the idea that they were intended to imitate the soft-paste wares of China.
They admit of being forced into early bloom, like the hyacinth and tulip. They vary with a white, creamy or yellow perianth, and a yellow, lemon, primrose or white cup or coronet; and, being richly fragrant, they are general favourites amongst spring flowers.
The whole surface of the ponderous upper storey is covered with a diaper pattern in slabs of creamy white Istrian stone and red Verona marble, giving a delicate rosy-orange hue to the building.
