I have had a ladyslipper in my garden for about 8 years. In fact, the small garden was built where it is now because the lady slipper was growing. Since the garden was planted, the ladyslipper leaves come up growing larger each year, but dosen't flower. It looks very healthy otherwise and the leaves last until the fall. I have tried adding extra compost, pine needles, etc. The other woodland flowers do fine. Any help ing producing a flower is appreciated. Thanks!
I live in the Lower Hudson Valley in a woodland area.
