I planted 12 crowns this year, each have 1 long stem, like a fern. How
do I care for the plants the rest of this year?

Water them well, keep the ferns alive to nourish the roots. :-)
I leave them in the winter and let them dry so they become a "frame" for
the cover sheet I cover the bed with. I cut the dead ferns down in the
spring.

The female ones will bloom and often produce a little red seed pod.
