I constantly dig up Kwanso every couple of years and put them by the curb with a sign that says "FREE". Surprisingly, once at the curb, they're usually gone before the next day.
Seeing how fast the ditch lilies disappeared from the curb, I assumed irises would be the same. Turns out, I haven't had much luck putting out irises. Even though they were "FREE", not many people took them.
