Tel, I've gone and harvested at sketchy places (the mall, gas stations...) where people have landscaped with non-native willow. I just happen to be surrounded by native willows where I live and feel less worried about harvesting. My solution for now is to go up to Dunbar Gardens in Mount Vernon and get basket willow sticks for creating my own willow garden. But that will take a year...
Jocelyn, I know. I
should have asked! Thanks for cross posting. My friends have tried to tell me spirea was also used, but I really doubt that.
