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.

Mag. Hort. 3(4): 129 (Apr 1837) 
Of roses, I think I may say with safety, he [Samuel Feast] has at least five hundred specimens, all of which promise very favorably. Besides which, he has many blooming plant 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 Kurtzii, a most beautiful tea rose, and Master Burke, the most dwarfish rose, I believe, in existence, occur to me at the moment a a sample.
