True, but… Recognize that only a small percentage of hostas will germinate from seed (look like the parent plant). It’s also crucial to remember that variegated hosta seeds rarely never mature into variegated plants. You can, however, quickly produce a big number of appealing plants. Hosta cultivars were developed from seed cultivated by home gardeners and hybridizers. (The remainder are other hostas’ sports or mutations.) Not all hostas produce seeds, and even those that do may not produce a pod from each bloom (see below). When pollinated, Hosta blossoms begin to develop pods. If the pods come off before they are fully ripe, the seeds inside are almost certainly bad.
Each pod will ripen in approximately 6-8 weeks after blossom (pollination). After that, the pods will become yellow and eventually dry out and break open. Before that happens, pick the pods or place a mesh (organza) bag over the pod to catch the seeds. You can carefully split the pods open to uncover the six chambers that store the seeds if you picked the pods. A little kernel at the end of a papery black wing contains each seed. The seeds are bad if the wings are white. I placed the seeds from each pod in a paper coin envelope with the parent hosta(s), date, and other information. You can rub off the papery wing after allowing them to dry for a few days, making it easier to plant only the kernels. As many as 20 at a time, I do this in the palm of one hand over waxed paper. Because each wing may not have a seed kernel, this makes it easier to count the seeds. One pod can produce 30 or more seeds, while some only have a handful. Seed-cleaning photos can be found here.
How do you get seeds from hosta plants?
After fertilization, Hosta seeds are ready after 30 days. Because most of you don’t keep a calendar, the easiest way to know is if a hosta’s top seed pods are dry and cracking open. You can collect the seeds by cracking open the other seed pods. When the seeds are ready, they will be black, dry, and papery.
Do hostas reseed themselves?
Yes, if the appropriate conditions exist, hostas can self-seed. Not all hosta cultivars, however, are fruitful. It’s possible that some of them won’t generate viable seeds. Furthermore, the new hostas may or may not look like the parent plant.
How long does it take to grow hostas from seed?
Hybridizing New Plants Seeds of Hosta Hosta Seeds to Plant: Seeds should be sown in cell packs or 2 inch pots, pressed into the soil, and slightly covered. Germination takes about 4-5 weeks when kept at 60°F. If not, place the container in a zip-lock bag and store it in the refrigerator for 4 weeks.
Are hostas bulbs or seeds?
Hostas are all hybrids, which means they are the offspring of at least two separate plants with diverse genomes. Multiple genetic parents are common in hostas. Hostas can also self-seed, resulting in a “selfed” hybrid, according to the Delaware Valley Hosta Society’s “Hosta Lingo” page.
Is it hard to grow hostas from seed?
Hostas are a popular plant among gardeners because they are easy to grow from seeds and maintain. If you wish to keep your Hosta seeds until the next spring, store them in the refrigerator in a jar for the winter.
Can you plant hosta seeds directly in the ground?
Hosta seeds thrive in soil that is warm, wet, and quick-draining. Individual pots are easier to work with than giant nursery flats, but any plastic nursery container with drainage holes at the bottom would do. Herbaceous perennials like hostas should be started in a potting mix made up of equal parts coir, perlite, and vermiculite, or in a commercial seed-starting mix, according to the Washington State University Master Gardener Program. A few hours before spreading the seeds, moisten the growth mix. Apply a thin layer of growing mix to a few seeds and press them into the soil surface.
Will hostas spread?
On the subject of “Do Hostas Spread?” I’ve come across a lot of conflicting information. So, right now, I’m going to do my best to clear the air!
Hostas can be transmitted via subterranean runners or seeds. The worst culprits are rhizomatous Hostas that spread through the soil. Almost endlessly, these varieties will spread. Non-rhizomatous variants form clusters that mature to a mature width. These can still spread by seed, but it’s much easier to keep track of.
