Galliarda flowers, when can they be seeded in the fall so they come up next spring?

And how deep should they be planted.

now. spread them on top of tilled, smoothed soil and then mulch lightly over them. some may sprout now, but you will see them in the spring.
Reply:Although I live in England I tend to leave my gallardia plants to their own devices and each year they self seed and come up again in the spring. This then gives me chance to transplant them into other areas when they are large enough.
