Kelway's Peonies.
Kelway, of England, has produced some very fine varieties, such as Baroness Schroeder, James Kelway, Lady Alexandra Duff, and various other sorts.
Summer Day. Was exhibited at Regent's Park by Messrs Kelway and Son. Langport, and was noteworthy for the size and doubleness of its flowers: each bloom measured 5 in. to 7 in. in diameter. The outside petals were broad, of considerable length and white, forming a beautiful guard to the center of small creamv-white petals.—The Gardening World. $2.00.

Chinese Pæonies from Langport.
Amongst the various specialities in hardy flowers grown by Messrs. Kelway and Son, Langport, Somerset, herbaceous Pæonies hold a prominent position. We are in receipt of a boxful of blooms cut with long stems, showing how suitable they are for filling vases and making up other floral decorations in the home. [...]
Very choice was that named Summer Day, being a perfectly double bloom with broad guard petals, and wholly white with just a shade of blush on the outer petals only. It was also scented. Quite different in its way was the semi-double Queen Alexandra, with pure white, broad incurved petals surrounding a mass of pale yellow stamens. These were the only pure white varieties in the consignment, but they serve to show what a range of colour and forms of flower have been developed from the original single white P. albiflora.

As a general thing, many of Kelway's varieties will have the sulks and refuse to blossom, on account of the conditions not suiting their case. They are like the Englishman coming from all the comforts of the old country, who cannot adapt himself to our frontiers and is always grumbling about "the blarsted country."
I make the following memorandum from many of his list:
Lady Curzon. No bloom in live years.
James Kelway. The same record.
Prince of Wales. One bloom in six years.
Mr. Brighton. No bloom.
Summer Day. Bloomed once, but had on a dress that did not belong to her.
Joan Seaton. Never a bloom.
