Virginia Waterleaf (Hydrophyllum virginianum)

Seed Collection Time:

Late spring to early summer — typically June through early July.

Signs seeds are ready:

• After flowering, the plant forms round, green seed capsules that turn brown and dry as they mature.

• Each capsule contains 2–4 hard, shiny black seeds about the size of a small BB.

• Capsules split open naturally when ripe, so check frequently to avoid losing seeds.

Seed collection steps:

1. Monitor capsules and collect when they are brown and beginning to split.

2. Place capsules in a paper bag or tray and allow them to air dry for several days.

3. Once dry, gently open the capsules to collect the seeds.

4. Store seeds in a cool, dry place, or stratify soon after.

Germination tip:

• Requires cold-moist stratification for 60–90 days for reliable germination.

• C(60–90): Mix seeds with moist medium and refrigerate, or sow in fall for natural stratification.

• Germination may be slow and irregular, so patience is advised.
