it and planted it in masses, producing flowers of a dazzling’ 
blue color. There was no blue flower that produced so’ 
brilliant an effect. It was more dwarfish than D. Sinen- 
sis, growing about two feet high, the stems not so flexible, 
and color much: finer; the flowers being double, I could 
never obtain seed. Another seedling, called Breck’s No. 
2, color purplish blue, with semi-double flowers and infe- 
rige to No. 1,1 did not care to propagate, and let it die. 
I believe the destruction of this beautiful variety was 
caused by little maggot-like worms, which worked in the 
roots. 
D. Henders6ni is a beautiful variety, raised by Mr. Hen- 
derson, a nurseryman of England; probably from D. ela- 
tum, which it very much resembles in growth and foliage. 
The flowers are sky-blue, with white centre, and are ar- 
ranged in long spikes. 
D. formésum.—This is a splendid species or hybrid va- 
riety, with large lively blue flowers, with the centre white, . 
shaded with reddish-purple; one of the most desirable 
hardy herbaceous plants in cultivation. It blooms from 
July to November, giving a supply of the most brilliant 
blue throughout the season. A. coclestinum is a variety, 
of formosum, or a hybrid. of elatum, with sky-blue flow- 
ers, equally hardy. There is also a large number of 
hybrid Delphiniums, partaking of the habit of elatum, 
which are beautiful; but these described, will be sufficient 
to make up a good edllection, 
D. cardinalis is found in Southern California.—I should 
doubt its existence, had I not seen specimens of the dried 
plant, which were of a brilliant scarlet. Isaw it in the 
herbarium of a gentleman, the editor of a paper in Los 
Angelos, who gathered it himself. It was advertised by 
some of the English and French nurserymen at about five 
dollars a plant. I ordered one from each place, when, to 
my great disappointment, it turned out to be D. puniceum,
