Grafting growth in the vascular cambium. Occasionally, a so-called "graft hybrid" or more accurately graft chimera can occur where the tissues of the stock continue to grow within the scion. Such a plant can produce flowers and foliage typical of both plants as well as shoots intermediate between the two. The best-known example this is probably +"Laburnocytisus" 'Adamii', a graft hybrid between "Laburnum" and "Cytisus", which originated in a nursery near Paris, France in 1825.
