Messrs. Barr & Son's Paeonies.
Double Flowered Varieties.
These form the major part of the collection and occupy by far the larger portion of the ground; and although at the time of our visit the display of bloom was yet in its infancy, many beds having yet to open, the following varieties were exceptionally noteworthy. 
Charles Verdier is both a pretty and a distinct variety, of dwarf and compact habit, bearing rather small flowers, which are, however, very neat, and of excellent shape and a rich glowing crimson in colour.
