Right now, my favorite rose is Reine des Violettes, a Hybrid Perpetual that has fuschia/violet colored blooms, hardly any thorns and a true-rose fragrance. Even the foliage is fragrant so when I deadhead it my hands smell seriously wonderful.
However, some of my new roses are going to be contenders. Tradescant is blooming its head off in the 100+ heat, bearing deep red blooms that are textured like butterfly wings. And Pat Austin (above) isn't stingy with its glowing orange/yellow/blush flowers.
