Stolons of Lilium nepalense. L. nepalense is a native of the Himalayas,growing at between 1000 and 3000m above sea level. Its growth habit is stoloniferous; the bulb develops a vertical flower-bearing stem,together with laterally extending horizontal stems (stolons). These grow beneath the surface of the soil,eventually terminating in a new shoot,and so propagating a new plant. In horticulture,this means that new plants may appear at a distance from the original bulb. The picture shows a plant of L. nepalense growing in a large 35cm diameter flowerpot. Under these confined conditions,the stolons have emerged from beneath the soil surface,before curving downwards to re-penetrate the soil. Clearly visible are developing roots in rings around the stolon. Under natural conditions,these roots (underground) would grow and feed the extending tip of the stolon | |
