ditto what the others said.
you really need to know which particular one you have. there are different requirements for each type - sunlight level, pruning needs, watering, etc.
a general rule of thumb is that they like their roots to be kept cool at all times so you'll want to make sure the roots are well covered with a thick layer of mulch or large stone or
plant something in front so that the roots are kept in the shade.
once they are established, they develep a LARGE root mass - so, over time, you'll want to make the covered area larger.
we've all had some extreme heat these last weeks and many areas have gotten lots of rain too...the combination of the high heat, dried out soil and then excessive rain will cause them to wilt a bit.
i'm seeing it with both of mine. just make sure that it's watered properly (if there is no rain) especially on the extremely hot days and it should be okay.
when it comes to blooming - without knowing which variety you have, we can't say whether you should do a light pruning or not. some will do a second bloom after a light trim and others won't. (some only bloom on last years growth and others will bloom on last years growth as well as this years)
