THE CULTIVATION OF PYRETHRUM.

home, and Dr. Radde\s statement is corroborated by a communication 
of Mr. S. M. Hutton, vice-consul general of the United States at Mos- 
cow, liussia, to whom we applied for seed of this species. He writes 
that his agents were not able to get more than about half a pound of 
the seed from any one person. From this statement it maybe inferred 
that the seeds have to be gathered from the wild and not from the cul- 
tivated plants. 
As to the Dalmatian plant, it is also said to be cultivated in its native 
home, but we can get DO definite information on this score, owing to the 
fact that the inhabitants are very unwilling to give any information regard- 
ing a plant the product of which they wish to monopolize. For similar 
reasons we have found great difficulty in obtaining even small quantities 
of the seed of P. cineraria/olium that w. s not baked, or in other ways 
tampered With, to prevent germination. Indeed, the people are so jeal- 
ous of their plant that to send the seed out of the country becomes a 
serious matter, in which life is risked. 
Cultivation 01 Pyrethrum. — The seed of Pyrethrum roseum is ob- 
tained with less difiiculty, at least in small quantities, and it has even 
become an article of commerce, several nurserymen here, as well as in 
Europe, advertising it in their catalogues. The species has been suc- 
cessfully grow n as a garden plant for its pale rose or bright pink flower- 
rays. Mr. Thomas Median, of ( lermantown, Pa., writes us: " I have had 
.1 plant of Vyrcthrum roseum in my herbaceous garden for many years 
past, and it holds its own without any care much better than many other 
things. I should say from this experience that it was a plant which will 
very easily accommodate itself to culture anywhere in the United States." 
Peter Henderson, of New York, another well-known and experienced 
nurseryman, writes: " 1 have grown the plant and its varieties for ten 
years. It is of the easiest cultivation, either by seeds or divisions. It 
now ramifies into a great variety of all shades, from white to deep crim- 
son, double and single, perfectly hardy here, and I think likely to be 
nearly everywhere on this continent." Dr. Barnard reports that " in 
the garden of the Starling plantation, on Lake Chicot, at Sunny Side, 
Ark., 1 found Pyrethrum which had been growing perennially for 
many years. This is toward the northern limit of the cotton belt 
and, for the river country, the most northern point of .serious in- 
juries from the Cotton Worm. Since the plant does not freeze out there 
it will certainly withstand the winter throughout the region of se- 
rious depredation from the worm." Dr. James C. Neal, of Archer, 
Fla., has also successfully grown Pyrethrum roseum and many varieties 
thereof, and other correspondents report similar favorable experience. 
None of them have found any special mode of cultivation uecessary. In 
185G Mr. C. Willemot made a serious attempt to introduce and cultivate 
the plant 50 on a large scale in France. As his account of the cultivation 
of Pyrethrum is the best we know of, we quote here his experience with 
but few slight omissions : " The soil best adapted to its culture should be
