That looks good. Let those babies grow undisturbed for a year. Wood chip mulch around them. Water them well. DON’T put them in fancy potting soil or compost, NO babying besides that water. Clay soil is best. Divide the most robust plants in the second full year, and then get more aggressive after that when the punishment for losing a single one is lower.

Also, put some chicken wire over the area where the ones are that didn’t come up. Often, your most tender ones are getting browsed by wildlife, and repeated beating back can kill them before they get established.
