Woody plants grown from stolons are seldom uniform in size and are not often so well rooted as those grown from cuttings (358). Some herbaceous plants are, how- ever, more readily propagated by stolons than by any other means. The offset by which the houseleek (Sempervivum) is so readily propa- gated, is a very short stolon that forms a single tuft of leaves at its apex. The cane of the black cap rasp- berry (Rubus occiden- tal-is) , which roots from the tip (Fig. 85), and ^"'- ^^- " ^^""'^^ °^ ^^'^ strawberry. the runner of the strawberry (Fig. 86), that forms a plant at each alternate node, are modified stolons. 348. Propagation by layers or layering. — The layer is an artificial stolon, , a branch that does not naturally grow downward, which is covered with or surrounded by moist soil or other media to stimulate the production of roots (88). The branch may be bent down and cov- ered, as is usually practiced with the grape, wisteria, etc., or the soil may be ridged up about the branch, as is done with the quince and paradise apple. In either case the terminal portion of the stem is commonly left uncovered. In the latter method, which is known as mound-layering (Fig. 87), the stems of the plant to be layered are usually cut off just above the surface of the ground in early spring, to stimulate the formation of.
