Michael notes:

This specimen of Jeffersonia dyphylla is growing in a stand of beach and maple forest a few feet from a small creek. The best place I
know of to view Twinleaf is in the Morris Tract just east of Goderich on the Maitland river. Apparently there are many rare species growing there.
Twinleaf is also abundant there, along the river in a mixed forest. Some of the species found in the Morris Tract are relics of glaciation -- arctic wildflowers.
I have never seen any of them because they are pretty difficult to get to due to the fact that they grow on steep limestone cliffs.
It is the only public land I know of where twinleaf grows but there are some areas close to Varna, Ontario which is where this specimen is growing on private land.
It seems to have lots of maidenhair fern, wild ginger and trout lillies growing in the same area.
The fruits which form on the twinleaf are conical capsules with a hinged "lid" which opens in late summer after the capsule has dried out fully.
This plant emerged about three weeks ago (April 8th approx) and the leaves continued to grow. I have never seen Twinleaf available from nurseries which deal with native plants
-- too bad because the leaves are somewhat striking.
Twinleaf is a member of the Barberry family which also includes the common Mayapple or Mandrake.
