172 On the general treatment of Verbenas. 



Tweedieana. This, however, is not the case. We do so be- 

 cause it is much better known. We have, in speaking of the lat- 

 ter, previously to this, remarked that, as a whole, we like it far 

 better than the former. Its growth is more free; its umbels of 

 flowers much larger, more profuse and finer formed: its habit 

 upright and more graceful; and its blossoms remain in perfection 

 a longer period. V. chamaedrifolia is more dazzling in its color; 

 but in every thing else it is [inferior to the Twediedwa. Both 

 are superb, but the latter, we think, will be the most generally ad- 

 mired. 



After detailing all the particulars of the cultivation of the cham- 

 sedrifolia it would be needless to repeat the same again here. 

 Suffice it to say that the Tweedieana may be treated in the same 

 manner, with some exceptions. It is less difficult of cultivation, 

 and does not require so much care in watering during the winter 

 season. It is upright in its habit, and well adapted for training on 

 trellises. Its growth is more rapid, and the plants, when growing 

 in pots, will require more frequent shiftings. 



The Tweediedna may be kept through the winter season in 

 perfect safety and in good condition in an ordinary green-house, 

 and, we doubt not, a parlor. It may be propagated either by cut- 

 tings or layers in the same manner as has been recommended 

 for the chamsedrifolia. Set the plants in any place either in 

 the frame, green-house or other situation. About the first of Feb- 

 ruary they will begin to grow, and from this period they should 

 have frequent shiftings. Plants may be grown to the height of 

 two or three feet by the middle of May, if they are duly encour- 

 aged, and if trained to a trellis, tastefully made, will present a most 

 gorgeous array of its splendid crimson blossoms. 



It is only a short time since this fine species was introduced 

 into the country; and we have therefore had no experience upon 

 its growth in the border; but, reasoning from analogy, we have no 

 doubt it will flourish in such a situation, treated just like the 

 chamaedrifolia. It will probably grow much more vigorously and 

 require more attention; the shoots extending themselves faster, 

 will need to be oftener tied up if trained upright, or pegged down 

 if trailing upon the surface of the soil. It will also need more 

 pruning, and the old flower stems should always be kept cut off". As 

 regards the method of training the plants it is altogether a matter of 

 taste. In pots we prefer its naturally upright habit; but in the 

 border we think it would display its attractions to better advan- 

 tage when trailing on the ground. A bed of this and another of 

 chamaedrifolia would be two superb objects. The latter would 

 afi'ord a more glittering array of individual flowers; but the for- 

 mer, in the redundancy of its rich corols, and in all that con- 

 stitutes gracefulness of habit, would claim the admiration of all. 



The species will no doubt be considerably cultivated the com-
