Ta genus Dahlia was first established by the celebrated botanist Cavanilles *, (in honour of Andrew 
Dahl, a Swedish botanist, not Dale an Eng)ishman,) for three lofty, thick-rooted, perennial plants, 
natives of the distant regions of Peru; but all of which we have had the recent pleasure of seeing 
F wing 3 gardens of our own happy country. They are extremely desirable and 
_ showy plants; and none of them more so than the present one; which was raised from seeds sent 
; from Madrid last spring, by the Right Hon. Lady Holland, and flowered last September and October, 
in the open ground, in her Ladyship’s collection at Holland House, Kensington ; where our drawing was 
lately made. It has acquired the stately height of near eight feet, with a circumference of three ; and 
makes indeed a truly specious appearance : but we do not expect it will ripen its seeds; the season 
being too far advanced to encourage any reasonable hope of that nature. 
_ The best mode of propagation should seem to be that of dividing its somewhat tuberous roots, after 
t é stems die down. As to treatment, we see no valid reason why it, and both the other Dabliz, (the 
ccinea and rosea,) should not be treated as hardy herbaceous plants ; placed in rich earth and a warm 
But as they are both rare and valuable, it may at present be safer to consider them as green- 
a dying down 3 when moisture must be administered with a sparing hand. 
_ There are considerable reasons for thinking that the pinnated Dahlia will hereafter be raised with double 
- flowers, because the figure in Cavanilles’ Icones, above cited, represents them nearly semi-double ; and 
the doubling of radiated syngenesious plants is well known to Aorticulturists to be a circumstance of 
pretty frequent occurrence. _ i :
