Native plants for a Cape Cod garden

Bloodroot (Sanguinaria canadensis) is slowly but surely establishing itself in the woodland garden. Three little plants two years ago have become a smallish colony of 7 or 8. The flowers are still shortlived as they are easily destroyed by rain and wind, but whatever time they had to attract insects must have been enough. I am happy to see several seed pods for the first time. I hope this means a more rapid expansion throughout the woodland corridor alongside my house. The softly jagged kidney shaped leaves remain visible all summer and fall, and provide a nice groundcover.
