While common milkweed does perform well in sandy soils and poor soils, it does need soil in order to thrive. If you do want to plant milkweed for migrating monarchs, you could do so in some containers.
There is a variety of milkweed, sandhill milkweed, that can be planted in sand dunes, but it is native to the southeast and only winter hardy in Zones 8 and 9.
