The plant has 1 or 2 light to dark yellow slipper flowers.
The lady slipper flower is a protected flower and is in danger of becoming extinct, due to the ever expanding urban sprawl, taking out wooded areas of our wilderness.
Unlike slipper flowers that shrivel and fall off the ovary after pollination, Phals turn their whole flower into the capsule.
I am thinking of the tender primulas, cinerarias and the slipper flowers or calceolarias.
Most people will not know that we we have lady slipper flowers in our backyard, because we won't tell them.
