ON HOYA CARNOSA. 37 



They generally produce their lovely blossoms during- the early spring 

 months, hailing the return of that delightful season with presenting an 

 array of beauty, and affording a delightful gale of perfume. The 

 greater portion of this ornamental tribe of plants are from New 

 Holland. They are generally very free growers and of easy culture. 

 I find them to grow vigorously in equal parts of good rich loam and 

 peat, having a quantity of Calais sand mixed therewith. I use a good 

 portion of drainage in the pots, and give the plants plenty of pot 

 room. This latter attention is necessary as the plants root so very 

 rapidly. In a soil as above described and giving a good drainage, a 

 very free supply of water is required, I always take care to let the 

 soil be dry before I give a fresh supply of water. I shift the plants 

 into larger pots immediately they bave done blooming, they then push 

 freely those young shoots which are the blooming ones for next 

 season. 



I would add a list of kinds here, but I think it unnecessary to do so, 

 as each kind are graceful in form, and beautiful in flower, and merit a 

 place in every greenhouse or conservatory. 



Many of the kinds strike root freely from cuttings, taking the 

 young shoots, I strike them in sandy loam, the greater portion being 

 sand, and place them where they get a little bottom peat. Those 

 kinds which I find do not root readily from cuttings, I have struck 

 from portions of the roots, inserting them, &c, as done to shoots, 

 leaving out the top part of each about an inch. I have never failed 

 to raise plants of any of the sorts by this method. I always cut the 

 lower portion of the root in a transverse direction close under an eye. 

 If this plan of striking was adopted with most kinds of greenhouse 

 plants, it would be found to succeed better than by taking shoots. The 

 roots not being liable to damp off as the shoots often do. I shall con- 

 tinue to send a few remarks upon plants for each successive number 

 of the Cabinet, if it meet the approval of the conductor. 



ARTICLE X.— ON THE TREATMENT OF THE HOYA CARNOSA. 



BY PRIMULA SCOTICA. 



Not having observed any reply to your Correspondent's question res- 

 pecting the treatment of the Hoya Carnosa, I send my gardener's 

 mode of treatment, which always succeeds admirably. He uses a 

 mixture of sand and heath .mould, and during the colder part of the 

 year, keeps the pots in the hothouse. Those plants of the Hoya Car- 

 nosa that are propagated by planting the leaf, are long in producing 

 any stem ; and it is better to procure a good offset, and lay it spirally 

 in a pot containing the above mixture, when a fine plant is rapidly 

 produced. This waxen-flowered plant shows to-advantage trained 

 along a rafter, or against a trellis, and requires the free access of air 

 and light.
