Bloodroot (Sanguinaria canadensis) in bloom right outside my front
door.  I saved these 20 something years ago and have moved them twice.  
Only two survived but through the years have seeded and made a small
colony of about 25 plants. I have seen patches numbering in the hundreds
and it is an amazing site on the side of the mountains.
Even though these plants only bloom for about a week, I highly
recommend them.  They bloom when few other plants do and have showy
blooms and disappear completely by mid-June.
The name bloodroot comes from the heavy rootstock, if snapped it will
bleed bright orange, the indians used this sap as an anti-stringent.
Bloodroot - Sanguinaria canadensis
Left - This is half
the colony, it is
about 2 feet wide.
  Right top - here you can see the
seedpod almost completely developed.
The pod is proctected by the thick
leaves.
Right bottom  - I pulled this leaf aside
so the form can be shown.  The leaves
themselves are about hand sized when
fully developed.
