Argh!!!! Enabling is sooooo true. I bought gertrude jeckyll, abraham darby, happy child, crown princ margaretta, ebb tide, golden celebration,ambridge and portlandia from heirloom roses and was surfing about trying to find more information on roses that can handle a shadier area.... when I found your post.... I live close to wrightwood in california. On the sunny side of the same mountain. Nice weather here. 1 hour from euro desert roses so I looked and looked and looked.. logged back on and re looked... why did I see that post... I ended up ordering lady overtoun, souv of wooton, surpassing beauty of woolverstone, gipsey boy, louise odier maybe I ordered that from heirloom... marie dermar, daniel and asta von parpart.... argh.. Hope I love them as much as I hope I will.... Fragrance and charm is a goal of my garden.

Hi Lady, no I didn't do the grafted. My friend who has skillful hands did it. I learned now. I will try it when those babies DR get bigger.

Same here in the SF bay area...half the time they never bloom if grown outdoors in pots-even when placed where it can get blazing hot on a summers day..I think it IS the cool nights of 60f and lower all through our spring-fall that really doesnt allow them to grow much or flower. I have two of the hardiest-a hybrid and A. arabicum,and they arent encouraging me to add any more.
