Bigleaf hydrangea (Hydrangea macrophylla 'Endless Summer® Summer Crush®') brings bold summer color to beds, borders, and patio pots. You get showy mophead blooms that can read raspberry red to purple, with fresh flowers produced through the season when the plant is kept evenly moist.
Plant it where you can provide morning sun and afternoon shade, or bright filtered light. In hotter climates, extra shade helps prevent wilt and sunscald, while good airflow helps keep foliage looking clean. A layer of mulch helps conserve moisture and moderates soil temperatures.
Give it rich, well-drained soil and regular watering during dry spells, especially in the first year and when grown in containers. Feed lightly in spring and again after the first flush of bloom if needed; avoid heavy late-season feeding that can push tender growth.
Because it is a reblooming selection, you can prune sparingly. Remove winter-damaged stems and spent flower heads back to a healthy set of buds, and do major shaping right after a bloom cycle if necessary. Protect from drying winter winds and salt spray, and water well before the ground freezes in colder areas.
