A number of insect species feed on scentless mayweed.
These early hybrids were vigorous with large flowers, but they were also scentless and had limited fertility.
European species with scentless yellow flowers, is also a neat alpine, and so is E. rupestre, which is desirable for the rock garden.
The flowers-4 to 7 inches across-are pure white with green sepals, slightly incurved, and nearly scentless.
They are creamy white, without a trace of color in the sepals or petals, which are longer and broader than in any other wild kind, and scentless.
