September Morn. A light pink sport of Prima Donna, developed on the Pacific Coast. Has a splendid, free growth, running 2 to 3 feet without pinching, and shows every sign of being a phenomenal Rose. The bud is rather short and the outer petals are fimbriated, giving the flower a novel appearance. September Morn has considerably more petals than the average forcing Rose and it is, without exception, the most sweetly scented of any Rose so far placed on the market.

September Morn.  Our Sensational New Light Pink Rose. Growth of the very strongest of any H. T. yet disseminated, throwing long, strong canes in rapid succession, 2 to 4 feet long; does not require pinching and will produce more high grade blooms than any Rose known. Buds very large and finely formed, opening well into large, full, double flowers of magnificent size and form; a wonderful keeper, lasting over a week after fully open, and retaining its color and fragrance, which is without question the sweetest found in any rose. The petals are large and of splendid substance, waved or undulated on the edges, giving the bloom a very beautiful and distinct appearance. The color is an exquisite shade of light flesh pink on the outer petals, shading to pure rose pink in the center, with a faint touch of deep golden-yellow at the very base of the petals. Without doubt the most rapturously beautiful color in a commercial rose, selling on sight and called for repeatedly, owing to its splendid keeping qualities and distinct coloring. We have this season 10,000 of it planted for cut flowers, and it has given the most gratifying returns of any rose we have grown. Foliage large, ample and not subject to mildew or spot. A splendid all-year-round rose, giving good returns every day in the year. Does not get soft in extremely hot weather, and will be found indispensable where high grade blooms are in demand during the hot months. We are propagating from select wood only, insuring good, strong, sturdy plants that will give maximum results. Own root stock only, from 2 1/2-in. pots, $30.00 per 100; $250.00 per 1000; 5000 for $1000.00.
