After the early-summer flower clusters, green blimp-shaped pods form. These open to reveal silky parachuted seeds. Emerges rather late in spring, so don't give up on 'm too early! Drought-tolerant. Attracts monarch butterflies.

After flowering, the elongated-blimp-shaped seedpods provide garden interest.
