we have seen. If the petals were smooth and flat, and the 

 umbels more circular it would be difficult to surpass it. 



Feasfs White. — Flowers, white, slightly tinged with pearl ; 

 petals, large, broad, nearly smooth, and slightly cupped ; um- 

 bels, very large but rather flat; habit, tolerably vigorous, 

 similar to delicatissima ; foliage, light green and pubescent. 

 It is slightly fragrant. This is the best white variety that 

 has been produced ; it has no pink or yellow tinge, as is the 

 case with most of the white varieties, but inclines to a pearly 

 shade, which always gives the flowers a clear appearance. A 

 pure white, of good properties is yet a desideratum. This 

 variety was also raised by Mr. Feast. 



Julia. — Flowers, bright rosy pink ; petals, very large, good 

 form, nearly smooth, and little cupped ; umbels, very large, 

 loose, and rather long ; habit, moderately vigorous and nearly 

 erect ; foliage rather narrow, slightly pubescent. Raised by 

 Mr. Buist of Philadelphia, and is one of the best pink varie- 

 ties we have seen; the color is very lively, and the large 

 flowers, as well as large umbels, render it exceedingly showy. 

 It a great improvement over other varieties of similar color. 



Art. V. Ipomma Learii as a summer jioioering cU/mber in 

 the open ground. By the Editor. 



Nothing can exceed the beauty of this species, the most 

 brilliant of the Convolvulus tribe, when planted out in the 

 ground and trained up in a pyramidal form. Its bright blue 

 flowers are produced in the greatest profusion, hundreds bemg 

 open at once, on a moderate-sized plant. No garden with a foot 

 of spare ground should be without this most elegant climber. 



The plants may be turned out at any time in June or July, 

 and as soon as they begin to run, three stakes may be put up 

 to each, in a triangular form, about a foot apart, and tied to- 

 gether at the top. On this the shoots should be carefully 

 trained up ; and so rapid is its growth that in a few weeks it 

 will run to the top, and form a pyramid of foliage studded 

 with azure blossoms, forming the most beautiful, as well as 

 the most conspicuous, object of the garden.
