292 GREEN-HOUSE OF REPOTTING. \_Oti. 



being only in a few collections , flowers rosy purple, in 

 terminal heads, and lateral bunches in great profusion; 

 blooms from January to May, and is of a peculiar fra- 

 grance. D. oleoides is what may be termed " ever-bloom 

 ing:" flowers of a lilac colour; leaves elliptic, lanceolate, 

 smooth. I), laiireola, Spurge laurel ; J). pontica, D. al- 

 pina, and 2). Cneorum, 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 ob- 

 served a few of the other species and varieties, we will 

 observe the treatment of these. P. sinensis, now prseni- 

 tens, 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 variety of it. Keep them in the shade, 

 and be careful that they are not over-watered during sum- 

 mer. As the stems of the plant become naked, at this re- 

 potting 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. albiflbra, colour 

 pure white and beautiful. P. p. dentiflora. 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.) 



Pseonia 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. moutan, Tree 

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

 blush colour, and semi-double. P. M. Banksii is the com- 

 mon Tree Pasony, and called in our collection P. moutan ; 

 it has a very large double blush flower, and is much ad- 

 mired. P. M. papaverdcea 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
