282 GREEN-HOUSE — OF REPOTTING. \_Octoher, 



collections, flowers rosy purple, in terminal heads, and late- 

 ral bunches in great profusion; blooms from January to 

 May, and is of a peculiar fragr^ince. D. oleoides is what 

 may be termed " ever-blooming :" flowers of a lilac color ; 

 leaves elliptic, lanceolate, smooth. D. lauHola, Spurge lau- 

 rel ; D. politico, D. alpmaj and D. Cnednim, are all fine 

 species, and in Europe are esteemed ornaments in the shrub- 

 bery, 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 treat- 

 ment of these. P. sinensis, now prcfinitens, known commonly 

 as China primrose; flowers pink, 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 propagation. 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 ofi" 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. albiflora, color pure 

 white and beautiful. P. p. dentljlora. 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 treat- 

 ment. 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.) 



Pseoaia mdutan : 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. moutan. Tree 

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

 blush color, and semi-double. P. M. Banl'sil is the common 

 Tree Paeony, and called in our collection P. moutan ; it has 

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

 31. papavcracca is a most magnificent variety; has large sin- 

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

 splendid rose-colored double variety^ and is scarce ; there are
