Pæonies at Long Ditton.
The nurseries of Messrs. Barr & Sons would at this season gladden the hearts of all lovers of hardy border flowers—more especially lovers of the beautiful Chinese Pæonies. [...] The double Chinese Pæonies are somewhat later than the single forms...with the exception of a few, of which mention may be made as early flowering sorts, such as Adelaide de Lache, carmine rose, very large; John Fraser, beautiful rose; Madame Furtado, rose pink; Belle Douaisienne, delicate blush, which passes off white; Comte de Paris, outer petals rose carmine, centre blush.
