flowers in such a vase will have an 

 admirable effect. In botanic par- 

 terres, only one plant of a species or 

 variety is planted ; and that ought to 

 be kept perfectly distinct from every 

 other by a space an inch or two in 

 width being left all round it ; but in 

 parterres for effect, the whole surface 

 of the bed ought to be covered with 

 the same kind of flower, and no part 

 of the soil should be seen. Hence, 

 for this kind of parterre, low-growing 

 plants, and trailers, or creepers, such 

 as Nierembergias, and Verbenas, are 

 most desirable ; and free-flowering tall 

 plants, such as Petunias and Dahlias, 

 ought to be pegged down. One of the 

 most useful plants for producing white 

 in parterres of effect is the common 

 Petunia, and for red the different 

 kinds of scarlet Pelargonium, or Ver- 

 bena Melindres. 



The laying out and planting of 

 parterres should always be attended 

 to by the ladies of the place, because 

 it requires a degree of taste and artist- 

 ical feeling which is very seldom to 

 be found among some gardeners to a 

 sufficient extent; and which, indeed, 

 can hardly be expected in many of 

 them. 



Pasque Flower.' — See Anemone. 



Passeri'na. — Thymeloea. — Spar- 

 row-wort. Most of the species are 

 Cape shrubs, which require a green- 

 house in England, and should be 

 grown in sandy peat ; but one species, 

 P. hirsuta, is a native of the South 

 of Europe, with small yellow flowers. 

 They are all more curious than beau- 

 tiful. 



PassifloW. — PasstftorecB. — The 

 Passion Flower. The common Pas- 

 sion Flower, Passiflora ccerulea, is a 

 very ornamental climber, which will 

 live in the open air in the climate of 

 London, flowering abundantly, and 

 ripening fruit every year. It requires 

 a good and somewhat loamy soil ; and 

 where the soil is light and sandy, a 



pit two feet deep and two feet square 

 should be dug out and filled with a 

 mixture of loam and peat. This pit 

 may appear large for a plant with 

 such a slender root and stem as the 

 Passion Flower ; but it will not thrive 

 unless plenty of room be allowed for 

 its roots, and, on this account, only 

 the dwarf species can be grown in a 

 pot. There are several kinds of Pas- 

 sionFlower which require a greenhouse, 

 and some very splendid ones that 

 cannot be grown without a stove. Of 

 the latter, the most beautiful is P. 

 Loudoni, the flowers of which are of 

 ai most brilliant crimson. Nearly all 

 the kinds ripen seed freely, and the 

 fruit, which is a kind of berry, is 

 eatable but insipid. All the kinds 

 hybridize freely, and thus many new 

 kinds may be raised. Some of these 

 hybrids are very beautiful, particularly 

 those raised from P. racemosa ; and 

 some of these raised between the 

 stove kinds and P. cceriilea are 

 nearly hardy. They are all easily 

 propagated by cuttings, which should 

 be made of the young shoots, and 

 struck in sand, in heat, under a bell- 

 glass. 



Passion Flower. — See Passiflora. 



Paterso^nia. — Iridecs. — A fibrous- 

 rooted genus of very beautiful plants, 

 natives of New Holland. They 

 should be grown in sandy loam and 

 peat, and increased by dividing the 

 root or by seeds. They require a 

 little protection during winter, and, 

 on this account, they are generally 

 grown in pots, and kept in a frame or 

 greenhouse. 



PaVia. — Hippocastanacece, or 

 JEsculacece. The American Horse- 

 chestnut or Buckeye. These plants 

 differ from the common horse-chestnut 

 in their fruit, which is in a smooth 

 husk, while that of the horse-chestnut 

 is in a rough husk. They derive 

 their American name of Buckeye from 

 the large brown spot on the side or
