Upright annual 1-3 ft. tall. Heads of white flowers with changing center colors to tell pollinators what's new. The pods are spectacles indeed, spiraling around the stem with such precision you feel you're reading the mathematical language of the world, & if you look down the stem from above, there is the primal vortex. Sandy soil. Seeds prefer cool soil, sow in fall or cold stratify 30 days. Zone 5
