DIANTHITS, L. PINK, CARNATION. 

 (CaryophyllacecB.) 



There are few flowers with as delicate and agreeable a fragrance as the pink and 

 carnation, and a garden without at least a few of the hardiest species and varieties 

 would be lacking some of the most useful plants. The number of hardy wild species 

 is very numerous, there being over one hundred, but of these there are a few which 

 are distinctly better than the others. The Garden Pink, Dianthus plumarius, is the 

 parent of many of the best cultivated varieties. Some of these are hardier than others, 

 the double white variety Mrs. Sinkins appearing to be the hardiest of the doubles; in 

 fact it is the only cultivated named variety of the Garden Pink, of those tested at 

 Ottawa, which may be called hardy, the others being either tender or comparatively 

 short lived. 



The carnation was derived from D. Caryophyllus. It is tenderer than the Garden 

 Pink, though with care it can be carried over at least one winter. The so-called 

 Alpine pinks have, for the most part, comparatively small flowers, but many of them 

 are quite hardy. Some of these are not scented. 



The pinks and carnations may be propagated from seeds, layers, or cuttings, the 

 seeds usually germinating well and the cuttings and layers striking readily. For best 

 results pinks should be planted in warm, well drained soil, which will dry off quickly 

 in the spring but which will retain moisture during the summer. The early spring is 

 the critical time with pinks. They should be protected with a light, loose covering of 

 straw in the autumn to guard them against the sudden changes of temperature in 

 winter or spring when the ground is bare and they are in a soft condition.
