Hybrid Tea.  

Deep yellow.  Strong fragrance.  25 to 40 petals.  Blooms in flushes throughout the season.  

USDA zone 7b and warmer.  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.  Requires spring freeze protection (see glossary - Spring freeze protection) .
