Plant Sale Text: Green milkweed may not be the most striking specimen in your garden but it may soon be one of your favorites. This plant has green cylindrical flowers that are best appreciated up close. Like other milkweed flowers, their architecture creates little traps for the feet of pollinators who land on them. As they pull themselves out of the flowers, they are covered with pollen which they carry to other flowers they visit. Drought tolerant.
