Native Hydrangea Double Feature

Oakleaf Hydrangea & Smooth Hydrangea

Hydrangeas are among the most loved flowering shrubs in the landscape, but did you know Missouri is home to beautiful native hydrangeas?

This week we're featuring two outstanding native species that offer months of blooms, support wildlife, and provide lasting beauty in the landscape.

Oakleaf Hydrangea

Hydrangea quercifolia

Why We Like It

Oakleaf Hydrangea is one of the hardest-working native shrubs you can plant. From its oversized white flower clusters in early summer to brilliant fall foliage and exfoliating bark in winter, it truly offers four seasons of interest.

Seasonal Interest

Spring: Fresh oak-shaped foliage emerges.

Summer: Large white blooms slowly mature to shades of pink.

Fall: Leaves turn stunning shades of burgundy, bronze, and crimson.

Winter: Peeling cinnamon-colored bark adds texture to the landscape.

Growing Conditions

Light: Partial shade with 4–6 hours of morning sun and afternoon shade.

Soil: Rich, moist, well-drained soil. Tolerates clay better than most hydrangeas.

Zones: 5–9

Size: Depending on variety:

• Dwarf: 3–4 feet

• Medium: 4–6 feet

• Large: up to 8 feet

Landscape Uses

Oakleaf Hydrangea is perfect for woodland gardens, natural privacy screens, borders, and focal points. Dwarf varieties pair beautifully with hostas and native ferns beneath mature trees.

Maintenance

Low maintenance overall. Remove dead or damaged branches as needed, and because it blooms on old wood, perform shaping immediately after flowering.

Smooth Hydrangea

Hydrangea arborescens

Why We Like It

Smooth Hydrangea is an easy-care native shrub known for its enormous white flower heads that bloom through much of the summer. Popular varieties like Annabelle and Incrediball make this a favorite for foundation plantings and cottage-style landscapes.

Seasonal Interest

Spring: Fresh green foliage emerges.

Summer: Large rounded white blooms begin in early to midsummer and continue until frost.

Fall: Flowers gradually dry, adding texture to the garden.

Winter: Strong branching provides winter structure.

Growing Conditions

Light: Partial shade with protection from hot afternoon sun.

Soil: Rich, moist, well-drained soil that is slightly acidic. Performs well in clay if drainage is good.

Zones: 3–9

Size: Typically 3–5 feet tall and wide, with dwarf selections available.

Landscape Uses

Excellent for foundation plantings, woodland borders, rain gardens, and informal hedges. It also combines beautifully with other native shrubs like St. John's Wort and Buttonbush to extend seasonal color.

Maintenance

In late winter or early spring, remove dead, diseased, or crossing branches and prune remaining stems to encourage vigorous new growth and abundant flowering.
