How to Collect Hydrangea Seeds

Hydrangea is a genus of woody, flowering perennials containing varieties suitable for growing in sun or partial shade. Although they prefer moist, rich soil, they will grow well in other types of soil, as long as they receive adequate moisture. Protect them from high winds; water evaporates easily from their large leaves. The seed capsules resemble little vessels or containers, and it is the source of part of its botanical name, “angeon,” which is a Greek word meaning “vessel.” The first half of its name, “hydra,” means “water.” Hydrangeas easily grow from seed. It’s so easy that seeds scattered on the ground in the garden in early spring will cause a large number of them to germinate.

Things You'll Need

Mature, drying hydrangea blossoms
Scissors
Paper lunch bag

Rubber band or string
Glass jar or paper envelope

Instructions

- 1
  Choose mature, dried hydrangea blossoms in late summer and early autumn. Choose blossoms that have lost their normal color and have faded to a tan shade.
- 2
  Cut the blossoms with a scissors, including a length of stem about 6 to 8 inches long, if possible.
- 3
  Insert the head of each blossom into a paper lunch bag. Secure the top of the bag around the stem of the hydrangea flower with a rubber band, tie it with a length of string or just hold it closed with your hand.
- 4
  Shake the bag, holding on to the stem of the hydrangea. The flower will release the seeds into the bottom of the bag.

  Remove the hydrangea flower from the bag and discard. Empty the seeds into a glass jar, paper envelope or other non-plastic container for storage. Plant the seeds immediately or store them until spring.
