Don Juan Climbing Rose is fragrant and heat tolerant.
My nose does NOT detect fragrance, but Joseph's Coat Climbing Rose has very pretty, varying blooms!! Be careful, it has vicious thorns!!
Fast forward two years:
Unfortunately, most of the Modern Roses I had planted were not very fragrant. Arid climates are problematic, as the lack of moisture inhibits "wafting" of fragrance. The best solution, I determined, was to search for the most fragrant roses, then plant them in my yard. My search revealed a completely new class of roses for me to research in earnest; Old Garden Roses. My love of roses ( actually addiction) was revitalized because I discovered that while the perfectly formed, stiff, upright nature of many modern roses is beautiful, I could not resist the equally matched beauty and charm of Old Garden Roses.
