I don't know where my landscape would be in August without four particular plant genuses: Phlox, Hydrangea, Hibiscus and Buddleia. These are the flowering staples that carry me into late summer, when I can start to look forward to fall foliage season. Yes, they receive help from this or that other flowering gem, and additional help from the plants that I grow for their foliage value, but those four are the real workhorses for me in the dog days of August.
The inclusion of butterfly bush (Buddleia) may trouble some. Butterfly bush, generally speaking, is an invasive plant in some regions. But are all types invasive? A new one named 'Blue Chip' just may not be (the jury's still out).
In what sense does 'Blue Chip' butterfly bush live up to its lofty appellation, which makes one think of "blue chip" stocks? The flower on mine doesn't really have a whole lot of blue color in it, frankly. But it's all about the (allegedly) non-invasiveness with this plant.
