Suepue’rp1a—{ Shephérdia argentia, commonly known as the Buffalo- 
berry, is a favourite shrub in American gardens, both on account of its 
blooming at a very early period in spring, and its fine appearance when, 
in autumn, its branches are thickly clad with rich clusters of crimson 
fruii, somewhat resembling, in colour and size, that of the common Cur- 
rant. Uhese berries are not only highly ornamental, but, when slightly 
touche? by the frost, are also very palatable, and make a good preserve. 
As the Buffalo-berry is a diecious shrub, bearing its male and female 
flowers on different plants, it is generally sent out from the Nurseries in 
pairs, and the two sexes should be planted near each other, in order to 
obtain fruit. Bees are very fond of the blossoms, and an admirable hedge 
may be formed of this shrub, it being compact and neat in its growth, 
armed with thorny branches, and bearing the shears remarkably well.—

Tropzotum.—The elegant blue Tropeolum, which has been so much 
talked of, flowered beautifully in Messrs. Veitch’s nursery at Exeter, in 
the autumn of 1842. There are two plants which appear to be different 
species: the one having dark blue flowers with a white centre, and the 
other being all pale blue. The habit of both plants is that of T. brachy- 
ceras, with tuberous roots; and they are natives of Chili, like most of the 
other perennial species. TJ. edule is a beautiful _ pecies, with bright 
orange and green flowers; and other fine species are expected soon to 
flower, from the great number of tubers sent to England from Chili in 
1840 and 1841. The choicer kinds of tuberous Tropeolum may be pro- 
pagated by grafting them on tubers of the commoner kinds, in the way 
already directed for grafting the Peony and the Dahlia.
