Large Shrubs
Large scale spaces need large scale plants. This combination planting of the native Bottlebrush Buckeye with a purple foliage Japanese Maple creates depth as well as contrasting textures. As a bonus, Bottlebrush Buckeye has large showy blooms in mid July and beautiful clear yellow foliage in the fall.
This plant is Bottlebrush Buckeye, one of the plants on your plan.
