1010 THE PRACTICAL GARDENER. [J(t?l. 



hardiest of all, or such as are denominated frame plants. It is 

 probable that plants would become, by degrees, under such 

 treatment, hardier in each succeeding generation. There are 

 some plants which now occupy a place in our shrubberies, which, 

 within our own remembrance, were kept in the stove, the genus 

 Camia, for example ; and many which, within the same period, 

 occupied a place in the green-house, are now treated as per- 

 fectly hardy, of these Aucuba japo?iica, Pceonia montan, Cov" 

 chorus japonica^ and many of the genus Cistus and 3Iagnolia, 

 may serve as examples. Most of the herbaceous green-house 

 plants, and all bulbs usually kept there may be reckoned as 

 amongst the most likely to stand our winters in such situations. 

 It is to be regretted that so little attention is paid to these two 

 last divisions of green-house plants, many of them possessing 

 great merits when in flower ; probably the want of foilage, or 

 continued verdure during a certain period of the year, may be 

 assigned as the cause of their scarcity in collections. Many 

 Cape bulbs of great beauty may be cultivated with little trouble, 

 and require no room in the gi'een house during winter, as they 

 are found to sustain no injury by being deposited in any dry 

 room or loft, either in the pots, or taken out of them during 

 the time of their inactivity. Many tuberous rooted plants may 

 be kept in the same way. 



PROPAGATING GREEN-HOUSE AND CONSERVATORY PLANTS. 



As some of these produce no seeds in this country, at least 

 many of the more valuable and scarce species, recourse is had 

 to the various other modes of propagation, such as by cuttings, 

 layers, grafting, budding, &c. ; but of these, that of propagat- 

 ing by cuttings is most generally adopted, and more speedily 

 accomplished. As all plants do not propagate by this method 

 with equal success ; some only by pieces of the old or r pened 

 wood, others by the young shoots, while quite soft and young, 

 different seasons, therefore, are chosen to suit the kind of plant, 

 its state of growth, &c. For some species this month is pre- 

 ferred, particularly with such as remain long in the cutting-pots 

 before they strike roots, as is the case with most hard wooded 

 plants. By beginning thus early, the young plants become
