them for their winter's rest. By no means, however, allow any of 

 them to remain out during drenching rains, although none of them 

 are so tender as serrulata ; and in placing them in the greenhouse for 

 the winter, it will not be necessary to be so particular in choosing a 

 place for them as in the former case, as they are not so delicate, so 

 that they have a nice airy light situation, and wintered moderately 

 dry. 



Most of the Boronias are very liable to the attacks of mildew, 

 which, if not kept in check, will ultimately destroy the plants. This 

 frequently makes its appearance in autumn after, and sometimes be- 

 fore, they are consigned to their winter quarters. As soon as it is 

 perceived apply sulphur, which entirely destroys it. I always found 

 sulphur to agree with their health, as I made a practice every autumn 

 of dusting the plants all over with it, and allowing it to remain upon 

 them until spring, when a syringe and some clean water will remove 

 it, and the plants then look green and healthy. 



The following are some of the best kinds of Boronias in cultiva- 

 tion : Anemonefolia, Fraserii, Pinnata, Tetrandra, Trifoliata.

DAHLIAS OF 1852. 



The following list, comprising the leading varieties sent out last 

 spring, is prepared with the view of assisting those who are not quite 

 conversant with their habits. 



Sir R. Whittington (Drummond). Figured in the March 

 Number of the Florist for 1852; ruby crimson, with broad smooth 

 petal; deep and perfect outline. Occasionally requires a few more 

 petals to make a full centre, i. e. not quite double enough ; but this 

 is probably when the plant is becoming exhausted, or from over pro- 

 pagation. Some varieties will not stand this ; but it improves those 

 that are liable to come with hard green eyes. Requires rich strong 

 soil, with a tolerable share of thinning of the shoots, and disbudding; 

 altogether a noble variety, and will stand a long time : 4 feet high. 



Annie Salter (Salter). Pale peach lilac of transparent delicacy ; 

 very smooth, fine formed petal, outline, and centre. Certainly the 

 most popular flower of the season. It is a bad keeper ; and there 

 being originally but few roots, the supply will not meet the demand : 

 3 feet high. 



George Villiers (Union). Dark purple ; stout petal, full and 

 good outline, medium size. Early blooms the best ; requires good 

 free growth and plenty of thinning ; an acquisition to this class : 3 

 feet high. 



Dr. Frampton (Rawlings). A Princess Radziwill flower ; not 

 so large, but an improvement in form. In fact the form is very 

 good, but it will rarely be large enough for exhibition ; good in 

 habit, and a very pleasing variety : 5 feet high. 



Triumphant (Keynes). Crimson puce, occasionally producing
