The new race of Single Dahlias, which is commanding so much attention in Europe, has not yet made its appearance to any extent in our country, but Mr. Wm. Falconer writes to the American Garden for November, from Cambridge, Mass., that "Mr. Cullingford, of London, an amateur horticulturist of most refined taste, sent me, last spring, some seeds of single dahlias saved from his own collection. These seedlings are now in blossom, and display a general beauty and excellence at once gratifying and surprising."
The Single Dahlia seems to rage in London, and it looks as though we should have a pretty severe attack here. I flowered them last season for the first time. They were very satisfactory, although there were several impediments to the best results; viz., I sowed my seed late, and the exceedingly dry fall was not at all favorable to free or fine flowering. They are as easily grown as the petunia. Seed was sown in April (it should have been done March 1st) in box in greenhouse, transplanted into two and a-half inch pots, shifted into four-inch, and planted out of doors. They grew very fast, and most of them made very bushy plants three feet high. I was surprised to find such large tubers; some had burst asunder the four-inch pots. Although my seeds were started in the greenhouse, would recommend using the cool ends. They might be easily started in the window box in the house, and when transplanted put into a cold frame until weather suitable for planting out should come. Some that were kept in pots were brought into the greenhouse and continued a long time in bloom, being much admired; if intended for house-blooming, which I think is the most advantageous way of using them, would advise growing them in six or seven-inch pots, plunged during the summer.
They did not bloom profusely with me, but were full of buds, and undoubtedly, had the weather been more favorable, they would have been covered with flowers. The colors were white, scarlet, dark red, orange and terra cotta shades.
