Hi Lucky Lady,
I think you are saying that you have a greenhouse grown azalea in a pot in the house and the leaves and flowers are all dry but the branches are still alive.* If you want to be sure, GENTLY scrape a branch to see if there is any green just under the bark.* If it's still green it's still alive.* Generally greenhouse raised azaleas don't survive outdoors.* I suspect yours either got dried out, too much heat from an indoor heat source or too much sun.* You need to be sure the plant isn't rootbound and unable to take up water.* Take a look here.

Not sure what's ailing your bleeding heart, but if it's dried up then it's not getting enough water or possibly has been oversprayed with an herbicide or pesticide.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
