Summary
The classic white smooth hydrangea look, scaled down for the front of the bed.
Smooth hydrangea is a native shrub of eastern North American woodlands, best known in gardens for big white blooms like the old ‘Annabelle’. Invincibelle Wee White® 2.0 packs that look onto a plant about 2 to 2.5 feet tall and wide. Its flowers open pure white and age to soft green, and the improved stems are strong enough to hold them upright.
The first flush opens in early summer, and new blooms keep forming on fresh growth through late summer and into fall. Spent flower heads can stay on the plant for winter texture or be cut and dried indoors.
Because it blooms on new wood, a hard winter or a heavy spring cutback never costs a season of flowers. That makes it dependable in cold climates, where bigleaf hydrangeas often fail to bloom. Its small size fits the front of a border, a low edge along a walk, or a patio container.
Care
Invincibelle Wee White® 2.0 Smooth Hydrangea Care
Plant in full sun to partial shade. Six or more hours of sun gives the strongest stems and most flowers. In hot southern summers, choose a spot with afternoon shade.
Give it well-drained soil that does not stay soggy. It grows in clay and in a wide range of soil types, and the flower color does not change with soil pH.
Water deeply once or twice a week through the first growing season, and during hot, dry spells after that. Smooth hydrangeas wilt in drought, so mulch helps keep the roots evenly moist.
Feed once in spring with a slow release fertilizer.
Prune in early spring before new growth starts, cutting the stems back by about one-third. It blooms on new wood, so this spring cut does not remove any flower buds. No deadheading is needed for rebloom.
Growing in Containers
Its compact size suits large patio pots. Use a container with drainage holes and a quality potting mix. Container plants dry out faster than plants in the ground, so check the soil often in summer, and feed lightly each spring. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
