Plant has striking red and yellow rocket-shaped blossoms that bloomed from mid-May to mid-June. It filled in during its third year of growth. Although visually attractive, we collected almost no insects at this hummingbird-pollinated plant, and zero natural enemies. This species was the least attractive to natural enemies in the early season and the entire growing season, with zero natural enemies.
