Anise Hyssop Black Adder, red & yellow barberry: Spanish Lavender blooms for a longer time than most lavenders do and it has lovely silvery foliage that will play well with these other shrubs when the flowers are finished.
This garden is massive but has so many fantastic plants, enjoy the colors and forms of this space. Eupatorium which is the tall pink plant in the background. Russian Sage in the front border. The annual Verbena Bonariensis and Sedum.
