Entering Rose Horticulture

The American Rose Society Judges specimen blooms exhibited in uni­form containers according to the following scale of points:

Form 25
Color 20
Substance 15
Stem and Foliage 20
Balance and Proportion 10
Size 10
Total 100

Form: exemplifies the highest type of an exhibition rose, having many petals; formed, high-pointed center, in the most perfect phase of its possible beauty. Generally, this is when the bloom is “half-to three fourths” open.

Color: should be clean, fresh, pure, clear, and typical of the best speci­men of that variety.

Substance: constitutes the quantity and quality of matter and turgid­ity in the petals. Texture, crispness, thickness, firmness, and stiffness of the petals must be sufficient to give stability and durability of form and finish to the bloom that determines the keeping quality of the rose.

Stem: must be primary, straight, with typical prickles or thorns; in pro­portion to the bloom; and of sufficient size and strength to support the bloom without undue bending. The length of the stem should be in proportion to the size of the bloom and should exhibit several five-or seven-leaflet leaves

Foliage: should be comparable in size with the bloom and stem, uni­formly spaced, typical of the variety in quantity, size and color. It should be clean and free of the following: spray and dust residue, disease and insect damage, and additives.

Balance and Proportion: The overall pleasing appearance of the specimen, the relationship of size, form and location of each part in relation to the whole.

Size: Refers to the actual dimensions of the bloom. Seven or eight points are awarded the average size of a variety.
