Weeding, another kind....

Non-native invasive plants, this time, not unwanted books. Today's site of the day: California Gardens, just cruising around trying to find plants that go well with an eastern exposure (for the front yard). I have partial sun there and varying soils. One bed is protected by trees and the other is a little more exposed with drier soil (clay?). I suck at soil analysis. The beds are stocked with the standard crape myrtle, azalea, camellia, ferns, a rose bush (pretty--don't know what kind). I want to get less standard without challenging the sun/soil constraints.
