Thunberg, and introduced into this country in 

 1804. Several of the varieties now known have 

 been raised in Italy, where these pretty roses 

 flourish and bear seed abundantly. In the neigh- 

 bourhood of Florence the Double Eed may be seen 

 climbing to an enormous extent, and large plants, 

 completely covered with thousands of its very 

 double and perfect flowers. The Single White is 

 also grown in Italy; from this I raised in 1837 

 several hundreds of seedlings ; the seed I received 

 from Signor Crivelli, of Como, an Italian rose 

 amateur, very much devoted to gardening ; all the 

 varieties of this family are interesting, as they 

 differ so much from other roses. Alba, or the 

 Double White, is rather a misnomer, for it is not 

 pure white, but rather a pale flesh-colour, pretty 

 and distinct. Grevillia, or the Seven Sisters' Rose, 

 is a vigorous climber, blooming in large clusters, 

 which show a curious diversity of colours; for 

 soon after expansion, the flowers change from 

 crimson to purplish rose ; and then to pale rose ; 

 so that in the clusters may be seen three or four 

 shades, from rose to deep purplish crimson. In 

 wet soils, it is often killed to the ground by the 

 winter's frost : even in warm situations, and if 

 covered with mats, it shoots so early tliat, when 

 uncovered, it cannot endure the cold of spring. It 

 would probably form a fine pillar rose if thatched 

 in November with green furze or whin, which 

 admits air, and yet keeps off the severity of the
