Some grow better here than others, but I suppose that may depend greatly on how wet the area is where they are planted. One thing to keep in mind is that often, it is not "user error" but the grower source. Example: I have recently re-landscaped a front yard for a friend & was surprised to see how many times the lavenders & rosemaries are started in mixtures heavy in peat. Rot can easily occur, especially if the juvenile plants are watered more than they need. Discouraging & irritating to source plants, then lose them to poor cultivation practices inflicted on them prior to purchase, especially when they are trendy ($$$$) & then scarce. I have had luck growing on my Echies in larger nursery pots so I have more control over drainage/slugs/Rabbits & the like. Perhaps best to start from seed in some instances...
