It’s time to gather the seeds when you hear them rattling within dried pods. Here are four techniques for gathering and obtaining hellebore seeds.
A Word of Warning:
When working with hellebore plants, it is best to use gloves. In sensitive individuals, contact with sap may result in a negative cutaneous reaction.
Harvest Flower Heads
Harvesting the complete flower head is the simplest approach to harvest seeds from your hellebore.
To achieve this, cut off the flower head over a paper shopping bag or bucket using sharp pruners.
After gathering all the desired flower heads, empty the contents of the bag or bucket onto a surface covered with newspaper or a clean towel. Rub the pods with your thumb and forefinger until the seeds come out.
After removing the chaff (dry plant material), gather the seeds in your preferred envelope, jar, or container. The chaff can be disposed of in the garden or on your compost heap.
Crumble Flower Heads
Use your thumb and forefinger to rub each flower head over a paper bag or pail so that the seed pods fall out if you don’t want to cut all the flower heads off your plant.
After that, empty the seed pods onto a good flat surface that has been covered with newspaper or a clean towel. Carefully separate the chaff from the seeds and place the seeds in the chosen envelope, jar, or container. Discard the chaff.
Bag Flower Heads
You can avoid losing any seeds by covering the flower heads with bags, or even the entire plant (as explained in the last technique below), which would also lessen the possibility of the plant self-seeding in undesirable locations.
Small drawstring mesh bags of fine-weave materials, such cotton or organza, may hold seeds as small as 1/16 of an inch without letting them fall through. You can make these bags yourself or buy them.
Some people enjoy using twine and old stockings. The bags should enable air to get through so as to prevent the flower heads from rotting in damp conditions.
Each bag needs to be big enough to fully enclose a flower head that is up to 4 inches in diameter.
Once you notice the sepals turning brown and the seed pods starting to form, place each flower head into a bag and secure the drawstring around the stem.
Every few days, shake the bags to look inside. You should hear a dry rattling sound when you shake the bags after 1-2 weeks, depending on how soon you placed the bags over the flower heads.
Snip the stem beneath a bag when it begins to rattle in order to get rid of the complete flower head.
Separate the seeds from the chaff using a newspaper or clean towel, then put the collected seeds in the container of your choosing. Put the chaff in the compost bin or garden.
Bag Entire Plants
If you want to prune your hellebores after they have completed flowering, you should follow this technique.
As mentioned above, you’ll need to get some drawstring mesh bags, but these need to be around 20 inches tall and broad, big enough to hold whole plants. To keep the seed heads from rotting in damp conditions, you must still make sure that the material allows for ventilation.
When the sepals start to turn brown and seed production is obvious (the seed pods may be green with brown hints), completely enclose each plant in a bag and attach the drawstring around the stem’s base.
If you wait too long to bag them, you run the danger of missing the moment when the pods start to fracture and release their seeds.
Every couple of days, gently shake each bag to hear for the rattling sound that means the seeds are ripe.
Use sharp pruners to cut the plant stems to the ground beneath the bag after you hear the dry seeds rattling so you can completely extract them. Hellebores are perennials, so the plants will reappear the next year.
In an appropriate receptacle, separate the seeds from the chaff after opening the bags over newspaper or a clean piece of fabric. Put the chaff in the compost bin or garden.
The first two are the simplest, but they might cause seeds to spill. However, you may always move seedlings if you discover them the following year in an undesirable location.
The advantage of the bag approaches is that they significantly lower the possibility of self-sowing. They work best, nevertheless, in dry environments. The seed within the bag could become moist and decay if it rains for an extended period of time.
Breeders, including home gardeners, who want to manually pollinate plants occasionally use bags to keep the plants away from the pollinators found in nature.
The use of bags has the disadvantage that you could unintentionally collect some immature seed.
Unripe seedpods that don’t rattle and don’t exhibit any cracks may be spread out to finish drying in a single layer on newspaper or a clean cloth in a dry, airy spot, even though seed that has matured on the plant has the best odds of viability.
The laborious process of bagging flower heads or entire plants is another drawback.
Try whichever technique or techniques you like. What best serves you in your garden should become apparent with a little experimentation!
As soon as you have your seeds, you must sow them at a depth of between 1/3 and 1/2 inch. The likelihood that they won’t germinate increases with storage time.
Hellebore seed does not keep well, and if it is not sown right after after harvest, it will need to undergo cold stratification.
