Night Scented Phlox -- Zaluzianskya ovata.
I ordered 4 of these online from Select Seeds. Due to packing, and heat only 3 survived. But I didn't want to complain.
I potted them into bigger pots to grow on (as the weathers been rough)... I know the tag says very well draining soil. I still have trouble with them though. 2 are okay if I barely water, all are now in cactus mix and watering is only if BONE DRY. One of the surviving 3 has some mildew on bottom leaves (too wet/cold?).... I was hoping to grow just these 3 in a container of suitable size. But they seem so tempermental, I'm afraid (i.e. if left out and it pours rain), even if in cactus soil. Has anyone had experience with these? Maybe they are a plant best for the ground?
