Hi Olvoyl!
Since you mentioned hydrangea, I'm assuming you are looking more for shrubs or bushes, rather than just
flowers. Am I correct?
I was thinking maybe some Hibiscus, Butterfly bushes or Shrub
roses. I have "Nearly Wild
rose" and they are awesome! Many businesses in our area use them in their landscaping and they are beautiful!
All of the above would do very well in the sun. Gardenias, however, do not fair very well if they are placed in direct, hot sunlight.
Of course, there are a variety of
flowers which will do beautifully in the sun.
I hope this helps!
Gardenia as a potted
plant indoors, keep it out of direct, hot sun, and allow it to only get bright light. ...
