And there's also my fern nursery. This began as a big planter of ferns, left on the property by the previous owner. The first couple of years I just tried to keep them watered. They seemed to get pretty withered in summer, but came back well in the spring. Knowing little about ferns, I started wondering what kind they were.
But mostly I like to take little clumps of rootstock - they are kind of nobby pieces from which the fiddleheads emerge - and transplant them into the yard. I always leave some rootstock to keep growing in the nursery for next year. The ferns do well in shade or part-shade, though they can take a fair amount of sun if you keep them well watered.
Here they are in a previous year, intermingled with Virginia bluebells.
