These roses typically have long pointed buds on long stems that offer an endless pallet of colors. All colors but blue and black can be found in hybrid teas. Perhaps of concern is the fact that in exchange for the perfect rose, with its perfect form and spectacular colors, an enormous amount of inbreeding has taken place. This has robbed many of the hybrid teas of the disease-resistance and winter hardiness that was found with many of the old roses. Another often mentioned is that hybrid teas no longer "smell like roses." In fact, many have lost their fragrance. However, with more than 6,000 varieties of hybrid teas available, it is possible to choose carefully from this pool and have hybrid teas that are vigorous and reliable. Many of the hybrid teas, floribundas, and grandifloras will require spray programs to maintain healthy foliage.
