Art. III. Experiments on the Vegetation of Rose Seeds.
By R. Buist, Florist, &c, Philadelphia.
Sir,—Some time last year I observed in your Magazine, a difference of opinion between two of your correspondents, in regard to the vegetating of rose seeds. I then determined on sowing some of the many varieties, and send you the result of my experiments.
No. 1. Seeds of Rosa indica odorata, or tea rose, were sown on the first of December, 1837, and vegetated in a temperature of between 58° and 65° Fahr., in from six weeks to three months, coming up occasionally during that period; the most of them have now bloomed, but not sufficiently strong to determine their character.
No. 2, of the same seed, and picked at the same time, was kept four weeks in sand, and sown on the ninth of January, 1838, and vegetated generally in seven weeks. The plants grew stronger and flowered better than No. 1, although treated in the same manner.
No. 3, seeds of the same, kept in sand till the first of February, and sown in pots and placed in dung or manure hot-bed, vegetated beautifully in six weeks, temperature from 65° to 75° Fahr., and are now promising, in growth, bloom and character, to surpass Nos. 1 and 2.
