ON THE DOUBLE CHINESE PRIMROSE. 



To the Editor of tlie Florist, Sir : As you invite communica- 

 tions from practical gardeners, I offer a few remarks on the above ; 

 as I think it a much rarer plant than it ought to be — few plants 

 excel it in simple beauty, and by proper management it may be 

 had in bloom every month in the year. Being double, it can only 

 be propagated by cuttings, which may be taken off at any time, and 

 readily struck in sand under a bell glass. In about three weeks 

 they are sufficiently rooted to pot into single pots. I find them to 

 thrive best in a compost of rough leaf mould and sandy loam, in 

 well drained pots. I repot them as often as they become well 

 rooted; and pinch off every flower stalk that appears till the plant 

 is six months old at least. I then let it flower on, and as each 

 flower truss shows symptoms of withering, pluck it out. By this 

 course it will continue to flower a whole year. They frequently 

 die out from exhaustion at this time, and the only way I find to 

 prevent this, is to divide the plant into off-sets, and so start with 

 them as with new plants. They always do well with me by this 

 treatment. The double white is the commonest and most easy to 

 be procured ; but I have observed in a report of the Pennsylva- 

 nia Society, fli&t the purple exists also in your neighborhood. 



If you think the above worthy of insertion in the Florist, I 

 should be happy to send ya'u some others when I have leisure. 



Yours, &c. Hortus.

 Hybrid Perpetual or Remontant Roses.-— This division of the 

 Rose was introduced to us about 15 or 16 years ago and according 

 to the opinions of good judges it originated between the perpet- 

 ual Rose Du Roi and the Bourbon Rose ; they have been till very 

 recently nearly all of a crimson or dark red color. Florists and 

 Rose-growers generally esteem these the finest of all Roses, to 

 which I would coincide, provided, they were constant monthly
