Hosta Seeds: What You Can and Cannot Grow From Them

This page does not recommend any seed product. We could not find a seed listing whose claims we could check, and extension guidance explains why: seed is the wrong way to get a particular hosta.

Seed does not reproduce the cultivar

NC State Extension notes that most hosta varieties will not produce the same variety as the parent when grown from seed. Every named hosta you can buy, from ‘Francee’ to ‘Sum and Substance’, is propagated by division or, in nurseries, by tissue culture (Iowa State), so that each plant is the same as the original. Iowa State notes that division preserves the leaf pattern of the parent plant — which is exactly what seed does not promise.

What growing from seed is actually for

Iowa State puts it simply: if you want to develop new cultivars, plants must be crossed and grown from seed. It advises collecting seed as soon as it ripens in the pods on the flower stalks and sowing outdoors 6 to 8 weeks before the last spring frost, or in pots indoors right after collecting. Seeds germinate in 15 to 90 days and the plants reach flowering size in three years. Every seedling is an unknown; the cultivars in the American Hosta Society registry are the few seedlings and sports that their breeders judged worth naming.

Warning signs in seed listings

• A cultivar name on a seed packet. Seed of ‘Blue Mouse Ears’ will not grow into ‘Blue Mouse Ears’.
• Colours hostas do not have. Iowa State lists hosta leaves as green, blue, yellow or chartreuse, often with margins in yellow, white, chartreuse, green or blue; red and purple appear only on the leaf stalks of some cultivars. Packets showing red, purple or rainbow leaves are not showing hostas.
• Very large counts (“100+”, “185+”) with no grower named and no harvest date.
• “Rare” or “giant” claims with no cultivar or seed parent you can look up.

When you do not need seed

• To get a specific hosta, buy a named plant or bare root, or divide a clump you already have. See bare-root hostas and how to divide and transplant hostas.
• To fill a bed cheaply, an unnamed bare-root mix flowers and fills in years sooner than seedlings.
