Tree Pæonies.—We are glad to see that these noble flowers are again likely to become popular, and that nurserymen are preparing for a possible large demand for them. Those who saw the lovely white variety, certificated recently at South Kensington under the name of Snowball, were fascinated with it, and the rich crimson sort, also shown by the same exhibitor, Mr. W. Gordon, of Twickenham, was also greatly admired. Mr. Gordon is, we are pleased to hear, importing these flowers direct from Japan, so that we may expect to see many beautiful sorts from that source.
