Audubon® Native Hydrangea
We currently do not deliver to your area at this time, please contact us to discuss other options.
Gardeners who grow Smooth Hydrangea almost always grow the form called ‘Annabelle’, or one much like it. That selection is a beauty, with big white flowers in huge, rounded bunches the size of cantaloupes. The problem is, those big white flowers are sterile, and offer nothing to wildlife. A better choice for pollinator-friendly gardens is the Smooth Hydrangea in its original, “unimproved” form, as we offer here. This Wild Hydrangea, as it is also known, is not as flashy as ‘Annabelle’, but it nourishes all kinds of native bees and beneficial wasps, flies, and beetles. Opt for substance over fashion!
May Benefit & Attract: cardinals & grosbeaks, wrens, sparrows, thrushes, orioles, finches, mockingbirds & thrashers, vireos

Recommended by Our Growers
Hikers exploring the woods during that blissful season between spring and summer may come across Smooth Hydrangea blooming in the understory. This native Accent prefers rocky outcroppings that aren’t too dry, but it can be found in any shady spot where the soil is moist but well-drained. It grows over a wide area, from New York to Georgia and west to Illinois and Oklahoma. Among the varied and interesting insects that visit Smooth Hydrangea are iridescent green sweat bees, gentle yellow-faced masked bees, tumbling flower beetles, and dance flies, which—in addition to visiting flowers—also prey on insect pests.
Another intriguing insect that relies on Smooth Hydrangea is the Hydrangea sphinx moth. Marbled like a tie-dyed t-shirt, with olive green, white, brown, and rusty orange streaks, it’s quite striking! Smooth Hydrangea is the primary plant it uses as a host for its caterpillars to feed on.
How to Grow
Smooth Hydrangea is a hardy, fast-growing, and easy-to-please American Accent. Give it a site in part sun or shade and irrigate regularly. The soil should be moist but not soggy and enriched with organic matter. This plant spreads by both seeds and underground stems, so it’s best to use it where its roaming ways will be welcomed. It is not overly aggressive, however. Smooth Hydrangea blooms on the new growth of the season, and you can prune it back hard in late winter if you like. Native bees may overwinter inside the stems; set the clippings aside so they can emerge safely when the weather warms.
