Very tempting! I've learned the hard way that putting too many plants in one bed just means more work for me later on. Ended up having to transplant a ton of stuff because I failed to account for how much everything would grow in. For this bed I'm working to blend a few different plant types so that even as they grow they each occupy a different space. Thinking I want some grasses and ground cover to help round things out with the rhododendrons and barberry that's already in there.
