Good post, Leslie -- thank you! I wonder what happens when they use their right-of-way to widen the road... do they then somehow have more right-of-way beyond the edge? This isn't something that directly affects me, we're set WAY back from the road, they can feel free to widen away if they want (maybe then they would at least dig the ditches out again), but in the nearest town they recently did a widening which practically put the highway on the doorstep of some houses
.
But, regarding the milkweed -- I would highly recommend buying seed to start plants from, rather than collecting established plants; many varieties of milkweed seed are available, and that way you are truly increasing the milkweed population.
