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. [...]
Amongst the lighter ones, Meteor Flight may be described as blush-white with a mass of narrow, pale yellow petals in the centre. British Empire is a similar style of flower, but the outer and broad, slightly fringed petals are clear rose.
