I raise my hand as another Houzz refugee. Gardenweb suited me well, but Houzz has taken all the beauty and ease of use of Gardenweb and swept it aside.
I live in the inland empire of southern California where it is hot and dry. The soil in my garden is sandy/rocky with some loam. My rose collection is probably one of the weirder ones. I really like species roses and have gathered many from around the world that appeal to me. I also like old garden roses and grow albas, gallicas, damasks, sweetbriers, rugosas, and hybrid perpetuals among others.
With all the drought on the horizon, I'm moving steadily towards growing more drought tolerant plants, especially California natives, including roses. Some of my favorites among these are Rosa minutifolia, Rosa minutifolia 'Pure Bea' and Rosa californica 'First Dawn'. I'm known for not treating my roses well--they need to be tough. I rarely if ever mulch, fertilize lightly and seldomly (hey the roses need to naturalize and get at least some of their nourishment from nitrogen-fixing companion plants), and water sparingly.
Here's a picture taken tonight of the first flower of the year on Rosa stellata mirifica which is native to New Mexico.
