Beyond Midnight bluebeard (Caryopteris × clandonensis 'Beyond Midnight') brings rich, deep blue flowers to your garden when many plants are winding down for the season. You will also love its dark, glossy foliage, which helps the blooms stand out and adds strong contrast in borders and mixed plantings.
Give it a sunny spot for the most flowers and the tightest, most compact shape. It will also tolerate part shade, especially where summers are hot, but flowering and foliage color are typically best with more sun. Plant in average, well-drained soil and avoid sites that stay wet, particularly in winter.
At maturity, this variety stays in the 24-30 inch range and fits easily into small spaces, foundation plantings, and front-of-border designs. It is a great choice for late-season color and for attracting pollinators. After it is established, it handles short dry spells better than many shrubs, but it will look its best with occasional deep watering during prolonged heat.
For easy care, cut the plant back in early spring before new growth takes off. This encourages fresh stems, a tidy mound, and a heavier late-summer bloom show. Mulch lightly to moderate soil temperature, keep the crown from sitting in soggy mulch, and you will have a reliable, repeatable performer year after year.
