Sorry but there are literally hundreds of azaleas that fit your description. You didn't even narrow down whether they were evergreen or deciduous. If they were properly when they were called dwarf azaleas, they will probably grow to be no more than 3' tall in 10 years but will not stop growing then, just slow down. If not treated properly with acidic soil, etc. they will actually get smaller in size until they die. HD gets good plants with good labels. It sound like they lost the labels on your plants. You may go to another HD and see if they have the plants with the labels. The rose looking azaleas are called double. The variegated azaleas are usually related to Japanese azaleas.

Search for Al Tapla's 5-1-1 mix or gritty mix. These potting mediums allow for fast drainage thus preventing root rot. Makes it difficult to over-water. Very worth the afternoon it takes to prepare and pot. Order some Foliage Pro as you'll need a fertilizer with micronutrients. Add a tiny bit of vinegar to the fertilizer water.

Here's what I read a long time ago on vermicomposters.ning.com. Citrus has a chemical in the rind that irritate worm's skin. It will break down like everything else, but the worms won't want to deal with it until after it's broken down. I don't know if freezing helps speed that process or not. They gave the name of the chemical, but that was probably 2-3 years ago. It was posted by someone who does worm research. (Kelly Slocum perhaps??) My feeling was that the chemical was in the outermost part of the rind. Since grapefruits have so much of the soft white part in comparison with the outer skin, I'll be they're not as much of a problem as oranges or lemon. I put some of my orange rinds in the bin and some down the disposal in the sink at the end of the day to get a fresher smell. As with any food whatsoever, start slow and see what happens. Some people put whole chicken carcasses in after getting as much of the meat off as possible. They bury them deeply and then months later take out the whole, clean smell-free bony part. If you burry the stuff that's going to smell bad under about 2 inches of mostly processed VC, it will get consumed and you can avoid the smell.

The citrus plants are responding well so far since being transplanted in the gritty mix. I have given each one a few showers with the hose. I gave them some vinegar mixed in with a gallon of water for each one. And I took off the tape and loosened the ties since this picture was taken. I am already planning what to order next time around, when the citrus I want become available again. ♡
