Carpinus caroliniana (American Hornbeam) [12 Seeds]


Germination Information: I recommend these seeds only for patient gardeners who have experience with challenging seeds. Sow about 1/2 inch deep. Apparently, these benefit from a warm-moist period first (about 2 months), then a natural or artificial chilling period of 2 to 3 months before a return to warmth. Or, you could just sow outdoors in mid fall to mid winter. If no seedlings appear in spring, leave the seeds outdoors through the summer, fall, and winter, and look for seedlings the following year. It’s normal for germination to be slow and irregular, with most sprouting in the second year after sowing.

Note that this information will not appear on the seed packet you receive.

American hornbeam (Carpinus caroliniana) is a deciduous, understory tree that typically reaches 25 to 30 feet tall. One distinctive feature of this species is its smooth, rippled, gray bark, which gives it another of its common names: musclewood. Male and female flowers are produced separately, in catkins, on the same plant. They’re not showy, but female catkins develop into interesting, winged structures, where you’ll find the seeds. The fall color tends to be showy shades of yellows, oranges, and reds. Native to eastern North America; these seeds are from wild plants growing here in Bucks County, PA. Ideal conditions are partial shade and moist soil. Zones 3 to 9.

2022-collected seeds are sold out. I hope to collect again around late September 2023. At least 12 seeds. PA ecotype. Shipping to US addresses only.
