Best container type (material) for hot sunny balcony?
Our balcony faces SW in california and has absolutely no shade (no overhang or balconies above). Right now all I have out there is some french lavender in a terra cotta pot. I want to do a herb garden and maybe some other plants but I'm not sure what material is best for the hot sun - I know terra cotta allows some moisture to escape, which is good in most situations but in the hot sun might not be best. I like the look of galvanized metal containers but I imagine they would cook the plants? Plastic is pretty ugly but if I can find some "stone-look" plastic or fiberglass would that be better or worse than ceramic (glazed, heavy) or unglazed terra cotta?
