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. [...]
The darkest of all was a crimson-red named Sir Dighton Probyn, almost the colour of the old red garden Pæony, but, of course, flowering much later, as this and all the others sent are garden forms of Pæonia albiflora.
