How to Grow Plantain lily (Hosta)

Plantain Lily can be grown from either seeds or roots. These can be sown/buried in either spring or summer.

Simply cover the seeds with topsoil, or bury roots at about 10 cm (4 inches).

They like to grow in a shaded area of the garden that has a moist slightly acidic to neutral pH of 5.5 to 7.

You can start Plantain lilies off indoors, but it is fairly hit and miss. They take from two weeks to three months to germinate at 10 degrees centigrade (50°F).

Once growing, transplant out at the beginning of spring with a spacing of 45 cm (18 inches; small Hosta varieties) or 90 to 120 cm (36-48 inches; larger species).
