Roses. — Mr. Cox, of the Durdham Down Nursery, has given a list of Roses, that answer admirably for grouping in this style of cultivation. The following kinds are what he enumerates, and which we extract from the "Magazine of Botany." Such might be obtained in pots, and supply for the present season's bloom.
Noisette. — Aimie Vibert, pure white; Narcisse, pale lemon; Ne plus Ultra, creamy-white; Ophirie, bright gold and salmon.
The above will bloom till frost arrest them. None of the kinds produce the green centres which some others are subject to. He recommends a bed of a sort, and contrasting the colours as distinctly as possible to produce the best effect.
