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. This small tree bears yellow flowers typical of "Laburnum anagyroides", purple flowers typical of "Cytisus purpureus" and curious coppery-pink flowers that show characteristics of both "parents".
Laburnum Avenue side of Richmond, including SR 5, U.S. Route 60 (US 60), I-64, SR 33, US 360, and US 1 and US 301. Laburnum Avenue begins at a trumpet interchange with SR 895 (Pocahontas Parkway) near Varina in southern Henrico County. The trumpet interchange, which is east of SR 895's mainline toll plaza, includes toll gantries on the ramps from southbound Laburnum Avenue to eastbound SR 895 and from westbound SR 895 to Laburnum Avenue. The highway heads north as a four-lane divided highway and intersects South Laburnum Avenue, which leads to Burning Tree Road and eventually Osborne Turnpike, then curves
