Hesperis matronalis (Illakko)

The species is origin is in Eurasia, but it has been in the gardens of northern Europe since at least 16th century. The flowers are usually bluish and have a pleasant odor, strongest at night. Because the plant belongs to the same family with cabbage it is a good food plant for many caterpillars. My first Hesperis had just this destiny. Before I noticed it was eaten to the ground. Fortunately the root was intact, so a new seedling appeared next spring, hopefully with better luck.
