Remarks on the Production of new varieties of different Flowers from Seed. By AN AMATEUR.

....You seem not to be aware, however, of the extent to which the practice has been carried in Baltimore. There is, at this time, an immense number of seedlings of all the plants you name in the collection of Samuel Feast, in this city, and all of them the product of very judicious cross impregnation.....Of roses, I think I may say with safety, he has at least five hundred specimens, all of which promise very favorably. Besides which, he has many blooming plants of excellent character, produced by him years ago. I am unable to name more than one or two, though I know he has a considerable collection. The Kúrtzii, a most beautiful tea rose, and Master Burke, the most dwarfish rose, I believe, in existence, occur to me at the moment as a sample....Baltimore, March 20, 1837.

Two roses, exhibited by Mr. Samuel Feast, excited general interest. They are quite new varieties, raised by him from seeds of the common Tea rose, very probably with an admixture of some other variety. The appearance of the plant and its foliage, is particularly neat; it grows very freely, and flowers beautifully, Blossoms large, and well colored, borne on graceful stems, with a singular fragrance, like that of the common Tea rose and the China rose combined. It has been named, in compliment to an amateur of the city, Kurtz's Rose, or Rosa Thea, var: Kurtzii.
