ii84 GREEN-HOUSE. OF REPOTTING. \0ctober 



tions, flowers rosy purple, in terminal heads, and lateral 

 bunches in great profusion ; blooms from January to May. 

 and is of a peculiar fragrance. D. oleoides is what may be 

 termed " ever-blooming :" flowers of a lilac colour; leaves 

 elliptic, lanceolate, smooth. D. laureola, Spurge laurel; D. 

 pontica, D. alpina, and D. Cnedrum, are all fine species, and 

 in Europe are esteemed ornaments in the shrubbery, but they 

 are not hardy in our vicinity. (Soil No. 15.) 



Primula. There are a few fine species and varieties in 

 this genus, adapted either for the green-house or rooms. All 

 the species and varieties will keep perfectly well in a frame, 

 except the China sorts. Having previously observed a few of 

 the other species and varieties, we will observe the treatment 

 of these. P. sinensis, known commonly as China primrose; 

 flowers pir.K, and in large proliferous umbels, flowering almost 

 through the whole year, but most profusely from January to 

 May. There is a double white and a double purple variety 

 that will always be scarce, from the slow method of their pro- 

 pagation. Keep them in the shade, and be careful that they 

 are not over-watered during summer. As the stems of the 

 plant become naked, at this repotting a few inches should be 

 taken off the bottom of the ball, and placing them in a larger 

 pot will allow the stems to be covered up to the leaves. P. 

 p. albfflora, colour pure white and beautiful. P. p. denti- 

 Jtora ; there is also a white variety of this, both similar to 

 the former two, only the flower indented or fringed. All 

 these require the same treatment. As they live only a few 

 years, many individuals, to propagate them, divide the stems, 

 which in most cases will utterly destroy them. The best, and 

 we may say the only method to increase them is from seed, 

 which they produce every year. (Soil No. 2.) 



Pazonia moutan: this magnificent plant and its varieties 

 are quite hardy with us, but most of them require the green- 

 house in northern latitudes. These are P. moutun, Tree 

 Paeony; the flower is about five inches in diameter, of a 

 blush colour, and semi-double. P. M. Banksii,-ia the common 

 Tree Pseony, and called in our collection P. moutan; it lia^ 

 a very large double blush flower, and is much admired. P. 

 M. papaveracea is a most magnificent variety; has large 

 single white flowers, with purple centres. P. M. rosea is a 

 splendid rose-coloured double variety, and is scarce; there art 

 also in China several other varieties, such as purple, scarlet.
