Medium yellow Hybrid Tea.
Registration name: Golden Wedding (hybrid tea, Krebs, 1938)

Bred by Alfred Krebs (United States, 1938).

Hybrid Tea.  

Yellow.  Average diameter 5".  Large, double (17-25 petals) bloom form.  Blooms in flushes throughout the season.  Pointed buds.  

Dark green, leathery foliage.  

USDA zone 6b and warmer.  Vigorous.  Spring Pruning: Remove old canes and dead or diseased wood and cut back canes that cross. In warmer climates, cut back the remaining canes by about one-third. In colder areas, you'll probably find you'll have to prune a little more than that.
