United States Patent CHRYSANTI-IEMUM PLANT Orville 0. Dunham, Niles, Mich., assignor to George J. Ball, Inc., West Chicago, 111-, a corporation of Illinois Filed July 27, 1959, Ser. No. 829,950

1 Claim. (Cl. 47-60) My present invention comprises a new and distinct variety of chrysanthemum plant, which is the result of crossing the variety Freedom (unpatented) a variety of my own introduction, and the unpatented variety Ermine.

The object of my invention has been to produce a new variety of chrysanthemum of the indicum type in which the plant habit is better than the parents and more compact with better flower form than such parents.

The development of my present new variety is the re sult of a careful program of selection and cross breeding in which generally speaking so-called American garden chrysanthemums have been crossed with the socalled English early chrysanthemums, in an endeavor to retain the best characteristics of each with a large number of different colors and an improvement in habits of growth, generally speaking.

The result of the specific hybridization previously mentioned has been to produce my present new and distinct variety of chrysanthemum plant characterized by the lighter than brilliant yellow, more closed center, white general tonality, and the large size and hardiness of its blooms, the very double arrangement of its petals, the earlier, continuous and long blooming period, and its better habit and larger and more abundant foliage. A very important advantage of the hybrids which have been generally referred to derived as a result of my program of hybridization, is to improve upon the habit of the English early chrysanthemums so as to produce varieties which are much more compact. However it is also desirable to take advantage of the continuous flowering feature of the English early chrysanthemum in contrast to the flowering of the American garden chrysanthemums which takes place over a very short period of time relatively speaking under ordinary conditions.

More specifically, the blooms of my new variety are of a pure white over-all general tonality with a lighter than brilliant yellow center, the center being very closed. (Nickerson Color Fan-Munsell Color Company.)

While my new variety bears a resemblance to both its parents, in the white over-all tonality, it has a much better plant habit than either and differs from other known varieties in many respects.

The comparison of the color of the blooms of my new variety with the color of the blooms of the variety Freedom calls attention to the fact that my new variety has the lighter than brilliant yellow closed center. In contrasting the plant of my new variety with the parent Ermine it is noted that the new variety is much more compact than Ermine which is quite tall. In addition the flower of Ermine has a tendency to show an open center whereas the flower of my new variety is quite closed.

Under the conditions of culture previously mentioned which took place in the region of Niles, Michigan, the plant habits and foliage of my new variety have appeared to be better than the parents, with the new variety being Patented Dec. 13, 1960 ICC ' more compact but much bushier with a somewhat spreading tendency.

The new variety when grown in the region of Niles, Michigan, blooms from mid-September and profusely and continuously until the killing frost.

The foliage of my new variety has been found to be more abundant and somewhat smoother texture and rather large generally.

My new variety has been asexually reproduced by cuttings, in the vicinity of Niles, Michigan.

My new variety has been found to retain its distinctive characteristics through successive asexual reproductions.

The accompanying drawing, forming a part'hereof, shows a typical plant of my new variety of chrysanthemum.
