feet. Suitable for such places as recommended for 

 Heracleum. 



Paonia. — The deep crimson P. officinalis when planted 

 in colonies in the grass makes a bright picture at flower- 

 ing time, the flesh-pink form being also very pretty. 

 As Paeonies must be strong to be ornamental it is well 

 to give them a rich and deep root-run to start with, to 

 keep the coarser herbage from crowding the plants, 

 and to apply stimulants in the shape of an occasional 

 mulch of hot-bed manure. 



Papaver. — The giant Oriental Poppy with its great 

 flowers of vivid scarlet glowing in the sunlight is one 

 of the most exhilarating sights in nature. It may be 

 grouped with telling effect outside shrubberies or by 

 open woodland glades. 



Polygonatum. — Solomon's Seal. A good plant for 

 semi-shaded spots in woods and by the waterside. Its 

 leaves have pretty autumnal tints. 



Polygonum. — P. cuspidatum is a fine plant for an 

 isolated position, and is particularly comely when 

 bearing its cream-white flower-panicles. It grows to 

 a height of eight feet, and soon forms a huge clump. 

 P. sachalineuse is another handsome species with larger 

 leaves and less conspicuous flowers. 



Pulmonaria. — Some of the strongest of these do well 

 under the shade of trees. 



Pyrethrum uligonosum. — A vigorous herbaceous plant, 

 six feet in height, bearing large, white daisy-like flowers 

 on graceful slender stems. 



Ranunculus aconitifolius. — This and its double variety, 

 known as Fair Maids of France, succeed if naturalised 

 in fairly moist soil and not allowed to become over- 

 grown. 



Rheum. — Rhubarb. One of the best of these is R. 

 Emodi which is a grand foliage plant. 



Rudbeckia. — Ornamental autumn-flowering plants.
