It is the height of monarch butterfly season in New Hampshire. Though fewer migrants have returned this year. They're producing the generation that will undertake one of the most impressive migrations: two-thousand miles to overwinter in Mexico.
Adult butterflies feed on the nectar of many different flowers but require very specific plants when laying their eggs. Eggs hatch into caterpillars that feed only on the leaves of particular species.
Among the most conspicuous wildflowers of early May, my favorite is a native wetland plant, the yellow so-called “Marsh Marigold.” It’s also called “American cowslip” and is always found blooming early in marshes, roadside ditches, fens and wet woodlands and at watery edges of damp pastures.
Marsh marigold is a hardy, native perennial. It’s considered to be one of the ancestral plants of the northern latitudes. It’s thought to have thrived in torrents of post-glacial melt-water following the last “glaciation” in the northern hemisphere.
Lovely woodland wildflowers are reliable “indicators” of soil moisture, fertility and light conditions. Wildflowers on the forest floor repeat patterns seen elsewhere each spring. The flowers speak to the patterns of why plants and trees grow where they do in our forests.
