FLORICULTURAL INTELLIGENCE 
Culture of the White and Purple Double-Flowered Rockets. —As 
soon as the plants have done flowering, cut the flower stems half-way down ; by 
so doing, several small shoots will appear at the uppermost part of the portion 
of the stem left remaining. Then draw a small quantity of soil round the stools, 
and, if the weather be dry, give them water at different times, afterwards make a 
bed under a south wall of equal parts of loam, leaf-soil, and sand. Next take off all 
the strongest shoots, either at the root, or at the upper part of the stalks, and 
plant them in the prepared bed. In about a month, go over them again, and 
take away all the strongest shoots, and plant them as before; for by so doing the 
shoots left have a better chance of growing. Continue the above practice until 
all the shoots are taken from the parent plants, which then generally die.—

order sol'ane^e. —The Nightshade Tribe. 
Nicoti'ana longifl'ora. —Long-flowered Tobacco. This curious species of 
tobacco forms another interesting addition to the flower-border; its long, slender, 
dingy white blossoms being produced in great abundance, and for several months 
in succession. The singular phenomenon, common to many white and dingy 
flowers, of expanding only at night, or in cloudy weather, occurs also in this 
plant. It is a native of Buenos Ayres, where it was discovered by Mr. Tweedie; 
and from seeds received from that enterprising collector, the plant was raised 
by M. Neill, of Cannon-Mills, near Edinburgh. Culture. —It is a half-hardy an¬ 
nual, thriving best in light rich soil, and is increased by seeds.— Sweet’s FI. Gar. 
Nicoti'ana pe'rsjca. —Shiraz Tobacco. This is rather a handsome annual, 
exhaling a faint but pleasant odour in the evening, at which time its white flow¬ 
ers are in perfection. In Persia, it grows three or four feet high. Culture. —It 
appears to require a dark rich soil, and most abundant watering during all the 
season of heat.— But. Reg. 
onagrariae. —The Evening Primrose Tribe. 
CEnoth'era densifl'ora. —Close-flowered Evening Primrose. A remarkable 
and new species, of which seeds were sent by Mr. Douglas, from Northern Cali¬ 
fornia, in 1831. It proves to be a hardy annual, bears numerous rose-coloured 
flowers of a small size, and produces abundance of seed. In some respects, this 
is different from the numerous species of Evening Primrose already in cultiva¬ 
tion. Its peculiar habit arises from each of the axillary buds of the main stem, 
which usually produce a single flower, developed into a short branch, itself bear¬ 
ing flowers in the axillae of its leaves. Upon the whole, Mr. Lindley is inclined 
to consider it a connecting link between Gaura and G.nothera.— Bot. Reg. 
pomaces. —The Apple Tribe. 
Amela'nchier flo'rida —Manv-flowered Amelanchier. A native of North- 
West America, where it was found by Mr. Douglas. It forms a handsome hardy 
shrub, in the way-of the Snowy Mespilus, flowering in May. Like that species it 
is best propagated by layers.
