...Garden lime is not quite the same as whiting. Some garden lime is closer to dolomite. And some contains what is enigmatically describes as "rock dust."
Okay, so you probably weren't wondering that. But I was, briefly, when I realized I had forgotten to pick up whiting on Thursday, in all the party excitement. I was hoping to save myself a trip to Portland, so I called Knight's Farm Supply. They do carry garden lime, but it is not straight calcium carbonate; there's apparently some magnesium in there as well, like dolomite, only who knows how much. Guess I am making the 110-mile round trip, which is a bigger deal now that I am driving Truckzilla.
On the other hand, whiting is a perfectly good substitute for garden lime on your perennials, to lower the acidity of soil. I don't use it, myself; my plantings pretty much have to sink or swim on their own.
Oh, gardening, I miss you. And it's not even officially winter yet.
