I am not aware that 

 either of these fine 

 plants is yet in Britain, 

 mucronata L'Her. Not 

 a hei'baceous species, 

 properly speaking ; 

 •when planted out, it 

 •will attain the height 

 of several feet, and 

 •will continue growing 

 throughout the year.

I have seen a tree 

 of this somewhere, 

 against a -walljthat had 

 stood for two or three 

 years, as marked on a 

 specimen in my her-

 neglected to note the 

 place, and at present 

 forget where.

And many other 

 species. I have tried 

 about 12 species of 

 this genus out, and am 

 convinced from the 

 result that nearly all 

 the species •will live

§ This rare climber was killed to the ground in 1838, but sprang up again 

 strong from the roots, in the Jardin desPlantes ; thus giving a kind of natural 

 evidence to prove how much we ought to guard against the direct rays of the 

 sun striking against the congealed trunks or stems of plants not truly hardy. 

 Had these roots not been surrounded by an opaque medium, thus preventing 

 the too sudden thawing, and consequent disruption of the vessels exposed 

 to the varying influence, their total destruction, I have no doubt, would have 

 been the result. Although, on the other hand, I am aware this will not al- 

 ways be the case, for there are a few plants whose roots seem to defy both sun 

 and frost to kill them, whilst their stems are comparatively tender. But I 

 think it will generally be allowed, and, in fact, the late severe winter has put it 

 almost beyond dispute, that the less we expose half-hardy plants to the influ- 

 ence of the sun, the more likely we are to succeed in inuring them to the 

 open air. 



II These will all stand against a wall if well protected, as will nearly all the
