I have the flowers inside by west facing window, one day i decided that the hour or 2 of direct sunlight they're getting through the window in the evening isn't enough, so one warm day i decided to put them on my porch, where they would get a bit more sun. It got up to almost 80 degrees that day, and the flowers got very droopy. so i put them back inside, watered them, and after almost a whole day, they perked back up. but the flower clusters were too heavy for the stems to get back up, so they stayed horizontal, while the flowers are stretching upwards, so they make a 90 degree angle. Those old clusters are almost bloomed out, at which point i'll cut them off. And there are new clusters growing and blooming, so the flowers are doing ok inside.
, if you plant them outside, they must be protected from frost, or a lot of direct sunlight. Aside from that they seem to be really easy to take care of.
, Good luck finding them! they make very pretty potted flowers, and I'm sure they'll look great in the yard also!!
I'm really enjoying them! i just wished they also has some fragrance!
