Fig. 5. Stocks For Roses. I. Manetti And De La Grifferaie

A, one year old plant of Manetti from a cutting inserted the previous autumn: a, portion of the stem from which the buds were cut clean out; b, the base of the stem cut previously below a joint, transversely, where a callus is formed and roots are emitted; c, the surface of the soil, indicating the depth at which the cutting was inserted; d, a strong, descending root, termed a tap root; c, side or lateral roots, usually more fibrous than the descending root; f, growth or shoots from above the ground: g, point where a bud is inserted in the summer after inserting the cutting in order to establish a Rose on the stock; h, point of shortening the strong root if the plant is lifted in the autumn after budding; i, points of cutting the top growth close in; j, point of cutting the stock back to the bud when this has started into growth.

Characteristics of the Manetti stock: abundant branching roots with many fibres, free growth, early and late, hence may be budded during September, on it Hybrid Perpetuals succeed admirably, adaptability to either light or strong soils, shoots moderately stout, very spiny, spines closely set, thin and very sharp, leaf composed of about thirteen leaflets, the plant forming a spreading, diffuse bush.

C, one year old plant of De la Grifferaie Rose (Cluster class, Rosa multiflora) from a cutting inserted the previous autumn: n, stem from which buds have been cut out; o, depth of inserting in the soil; p, strong descending root; q, stout and rather long side roots; r, relatively short and fibrous roots; 8, strong top growths; t, point of shortening the descending root; u, point of shortening the side roots to induce fibres to form near the stem; v, point of budding.

D, two year old plants of De la Grifferaie, showing the result of shortening the strong roots: w, descending stronger root, which in planting should be spread out nearly horizontally; x, stout side roots, also to be spread semi-horizontally at planting; y, fibrous roots carefully preserved at planting, result a much branched fibrous formation near the stem; z, point where a shoot was cut off close to a stem; a, growth from a shoot shortened at planting to two buds; b, depth of planting; c, point of budding or grafting.

Characteristics of De la Grifferaie: Strong, extended root formation, both deep and wide, very vigorous habit, shoots strong, joints rather distant, the shoots often growing 10 feet or more in length in one season, very long and strong spines, distantly placed as compared with the Manetti, foliage fine, leaf usually composed of seven leaflets, much larger than the Manetti.
