How to Remove Seeds From a Hardy Hibiscus Flower
The hardy hibiscus possesses long, slender stems with glossy, green leaves and some of the largest flowers of any perennial. Colors range from pure white to yellow, orange, pink or red. You can propagate hardy hibiscus seeds by collecting them from pods. Seeds of the hardy hibiscus are relatively easy to germinate, with some special attention. When planting, partly remove the seed coat to reveal the inner seed. This will allow it to better absorb water and oxygen. Plant seeds outdoors in the spring or indoors for the best chance of germination.
Collecting Hardy Hibiscus Seeds
- Collect seed pods when they turn from green to tan or brown.
- Place the pods in a large bowl and break them apart to remove the seeds from the pods once they are fully ripened.
Collect seed pods when they turn from green to tan or brown. The pods will develop a brittle and papery outer shell with the seeds inside.
Watch your hardy hibiscus plant to time gathering with the ripeness of the pods. Gather too early, and the seeds may not be viable -- too late, and the seed pods will have already scattered their seeds.
Place the hibiscus seed pods you collect in a paper bag and seal it. Write the plant name, date, place it was gathered any any other important information to make it easier to identify the seeds later.
Put the bag in a dry, well-ventilated place for the next few weeks to allow the seed pods to ripen further.
Place the pods in a large bowl and break them apart to remove the seeds from the pods once they are fully ripened. Remove the chaff from any seeds.
Separate the seeds and place them in a small container or envelope and label it accordingly.
Grow Hardy Hibiscus Seeds
Several varieties of the late-summer scene-stealer hibiscus are hardy even where climates are less than tropical, including rose mallow (Hibiscus moscheutos; USDA zones 5 through 10), rose of Sharon (Hibiscus syriacus; USDA zones 5 through 9), Texas star hibiscus (Hibiscus coccineus; USDA zones 6 through 9) and confederate rose (Hibiscus mutabilis; USDA zones 7 through 9). Nick the hard seed coat at the wider, rounded end of the seed with a clean craft knife. Cover the tray with its included clear plastic dome or with plastic wrap to keep moisture in. Ensure the soil is moist but not soggy. Water enough to keep the potting soil evenly moist, never letting it dry out or become waterlogged. Transplant the seedlings to separate 1-gallon containers filled with standard potting soil when they have at least three sets of leaves. Place the towel in a plastic bag and set it in a warm location, such as on top of the refrigerator or on a seed-starting heat mat, for about a week. If all or some of them do, your hibiscus produces viable seed you can sow.
Because hardy hibiscus seeds are pollinated from unknown sources, the color of the resulting flowers may not match those of the parent plant.
