PAPAVER. 



THE ENGLISH FLOWER GARDEN. 



PASSIFLORA. 



Mary Campbell, very full and finely fringed ; 

 White Swan, also white ; and Cardinal, with 

 fiery red flowers, very large and full, with 

 fringed petals. Crossed and recrossed with 

 the Eastern Poppy, yet another race has re- 

 cently sprung from this species in 'France, and 

 a dwarf one comes from China. P. setigerum 

 is a hairy form of the Opium Poppy, with 

 violet flowers. The Opium Poppy and its 



Parnassia palustris (Grass of Parnassus). 



varieties are treated as hardy annuals in the 

 same way as the garden form of the Corn 

 Poppy. 



P. umbrosum. A brilliant annual, about 

 2 feet high, like the common field poppy, but 

 of a darker red, arid with a jet black blotch at 

 the base of each petal conspicuous both inside 

 and out, making masses of this plant showy in 

 early summer. A compact form has arisen 

 under cultivation, and one with double flowers. 

 Seeds should be sown in autumn, in order to 

 secure strong plants for the ensuing summer. 

 Caucasus. 



P. arenarium is a showy annual from 

 the Caucasus, bearing purple flowers with 

 dark spots. Other handsome poppies, such 

 as Pleldreichti and spicattit/i, both from Asia 

 Minor, with orange and brick-red flowers 

 respectively, are perennials of easy culture. 



Paradisia. See ANTHERICUM. 



PARNASSIA (Grass of Parnassus}. 

 Pretty perennials for the bog-garden. 

 In our moist heaths and bogs Par- 

 nassia palustris is frequent, and a very 

 pretty plant it is handsome enough to 

 cultivate in moist spots, where it will grow 



as in its native haunts. Three other 

 kinds, natives of North America, are 

 quite as showy. P. fijnbriata has large 

 flowers with peculiar fringe-like append- 

 ages, its kidney- shaped leaves resembling 

 those of P. asarifolia, another hardy 

 species, about 9 in. high, which bears 

 similar white flowers without fringes. P. 

 caroliniana differs from P. asarifolia in 

 having oval or heart-shaped leaves ; it 

 flowers about the same time, usually from 

 the beginning of July till the end of 

 August. These hardy Parnassias thrive 

 best in a moist peaty soil or a spongy 

 bog. Seed, division. Saxifrage order. 



PAROCHETUS (Shamrock Pea}. P. 

 comimmis is a beautiful little creeping per- 

 ennial with Clover-like leaves, 2 to 3 in. 

 high, bearing in spring Pea-shaped 

 blossoms of a beautiful blue. It is of 

 easy culture in warm positions on the 

 rock-garden and the choice border, and 

 where the climate is too cold to grow it in 

 the open air it may be grown in a cold 

 frame or in baskets in the greenhouse. 

 Division or seed. Nepaul. Leguminosae. 



PARROTIA (Iron Tree}. Low Hazel- 

 like trees, natives of Northern India and 

 Persia, less remarkable for their beauty of 

 flower than for fine colour in autumn, when 

 the leaves give a mixture of crimson, 

 orange, and yellow, unique among hardy 

 trees. The best known is the Persian, 

 P. persica, which is hardy at least in 

 southern England. It does best in light 

 soils and grows well against walls with a 

 south or south-east aspect. Seeds, layers, 

 or greenwood cuttings. 



PARRYA. A small group of dwarf 

 perennial herbs from high mountain or 

 arctic -regions, with thick rootstocks, 

 narrow leaves, and showy flowers in 

 white, rose, or purple, and rather like a 

 dwarf Hesperis in effect. They are easily 

 grown in the rock-garden in ordinary 

 soil, and increase by division. Very few 

 kinds are in cultivation, though several 

 are well worth growing, such as P. intc- 

 gerrima, with pretty purple flowers in 

 April and May ; P. nudicaulis, a charm- 

 ing plant with large lilac flowers in early 

 summer ; and P. Menziesti, from N.W. 

 America, with soft rosy or deep purple 

 flowers in spikes of 6 inches. 



PASSIFLORA (Passion-flower). The 

 hardy blue Passion-flower, P. ccerttlea, so 

 often seen as a wall-climber in southern dis- 

 tricts, from its beauty and distinctness de- 

 serves to be grown wherever the climate 

 permits. It is not so suitable for arbours or 

 trellises as for walls ; the heat from the walls 

 aids in ripening the wood, and so enables it 

 to withstand the winter. A southern aspect
