Hydrangea arborescens (Wild Hydrangea) [25 Seeds]


Germination Information: I recommend these seeds for experienced seed-starters only, because they are very tiny and require careful handling. Scatter the seeds as evenly as possible over the surface of moist growing medium, gently press them in, and then set the pot in a warm, bright place. I find it helpful to enclose the pot in a plastic bag to create very humid conditions around the seeds; otherwise, they can easily dry out at some point during the few weeks they usually need to sprout.

Wild hydrangea (Hydrangea arborescens), also known as smooth hydrangea or sevenbark, grows as a mounded, multi-stemmed shrub in the range of 3 to 6 feet tall, with heads of white flowers through much of the summer, plus yellow fall foliage color. The dried seedheads last through the winter, catching the snow and ice and adding another season of interest.

I started with a pack of seed about 20 years ago, and that produced some plants with mophead-type domes of mostly sterile florets and some plants with flat, lacecap-type heads, with many small, creamy white fertile florets surrounded by a loose ring of the larger sterile florets. Both types self-sowed over the years, moving out of the sunny site I started them in and ending up in the small amount of afternoon shade my garden can provide. These seeds are from one of my favorite self-sown seedlings: a lovely lacecap type. I suspect these seeds will produce similar-looking plants, but it’s certainly possible that the flower forms might vary.

Partial shade is usually best: ideally light all-day shade or morning sun and afternoon shade. Wild hydrangea attracts bumblebees and some butterflies, so if you’re looking to add some pollinator-supporting plants in shade, this dependable, eastern US native shrub is definitely worth a try. Zones 3 to 9.

Collected in late October to early November 2023. At least 25 seeds. Unknown ecotype. Shipping to US addresses only.
