I adore my Louise Odier. I was a bit worried about how she would do for me, after reading here that Louise Odier is not a rose for warm climates. I live in Southern California, Zone 10a. We get some days over 100F every summer, but most Sum­mer days are between 85F and 95F. It usually cools down at night to 60F-70F(sum­mer nights).We get no winter chill, with a light frost on the lawn a few mornings per year. Yet, my Louise Odier bloomed from late April to early October this year. I purchased her as a tiny band sized plant in the fall of 2015. She lived in a large(15 gallon) pot from July of 2016 until late February of 2017. At that time I planted her into a new raised bed. She began blooming about 6 weeks later, and continued blooming for nearly 6 months. Sometimes there was only a bloom or two, but there were always new buds waiting in the wings. My Louise Odier is two years old and approximately 6’ tall x 7’ wide.My soil is mostly clay, and I amend it with homemade compost and chicken manure. My soil and water are both pretty alkaline. I do use some gypsum in each planting hole. So far, Louise Odier had exceeded my expectations. I never thought she would bloom so much, especially through the heat of summer. I love her bright pink, fragrantly scented, large blooms. They make good cut flowers with long straight stems. I can’t comment about blackspot, because my climate is just too dry for it. Powdery mildew however, is a constant battle for many of my roses. Louise Odier has never suffered from powdery mildew, not even when almost all my other roses had it to some degree. I love Louise Odier, and she’s thriving in THIS warm climate:) Lisa
