In the wild, all hosta species have the ability to reproduce by seed but some are more prolific than others. Therefore, seeds can develop through fertilization with pollen from the same plant i.e. self-pollination a.k.a. selfing, or pollen from another plant i.e. cross-pollination.
Do hostas multiply?
Tip. Versatile and easy to grow, most hosta varieties spread readily once they are established. They grow from rhizomes that spread just below soil level, and healthy clumps of hostas can be divided into smaller clumps every few years to share with friends, family and neighbors.
How do hostas spread?
Hostas can spread, either through underground runners or seeds. Rhizomatous Hostas that spread underneath the soil are the worst offenders. These varieties will spread almost indefinitely. Non-Rhizomatous varieties will grow in clumps that reach a mature width.
How do you get seeds from hostas?

How quick do hostas spread?
They grow slowly and may take two to four years to attain their full size, longer for the largest species and cultivars. Allow plenty of room when you plant to accommodate for their mature size. Small varieties spread three times as wide as they are tall.
How long does it take for hostas to multiply?
How fast do hostas multiply? It all depends on the variety. Vigorous hosta varieties grow to size within two years when they can be divided. Most varieties need 3-4 years to do this.
Do hostas self propagate?
Yes, hostas are capable of self-seeding, provided the right environment exists. However, not all hosta cultivars are fertile. Some of them may not produce viable seeds. Also, the resulting hostas may or may not end up resembling the parent plant.
Do hostas get bigger every year?
Hostas are perennials, which means they will come back bigger and better every year. Most hostas grow well in Zones 3 to 9. These versatile shade plants form a mound of leaves but vary greatly by variety, offering differences in plant size, leaf shape, and leaf color.
Are hosta plants invasive?

Can you plant hosta seed pods?
If your hosta flowers are pollinated, they will produce green hosta flower pods. After four to eight weeks, the pods will become yellow as they dry out, then split open. Within each pod are six chambers that hold the seeds. Sow the seeds shallowly in a sterile potting mix.
How far apart should you plant hostas?
Soil Conditions: Hostas can survive in a wide range of soils but prefer a rich, moist soil, high in organic matter. Correct Spacing: Depending the variety, space plants 1 to 4 feet apart. Planting closer with allow the plants to fill in faster creating a ground cover of hosta.

The eyes might be green or purple, or even white if they have been covered by mulch or leaves. Each fall hostas die completely down to the ground and yet each spring they come back bigger and with more eyes and leaves than they had the year before.
How long does it take hostas to grow from bare root?
