Buttercup flowers april11/29/2023 ![]() Swamp Buttercup ( Ranunculus hispidus) is the first of three related plants on our list. It grows in in a variety of shaded and partially-shaded habitats including wet woodlands, floodplains, and shady meadows. The colony spreads both by seeds and by thick rhizomes. In large doses, this toxin may be deadly. The plant contains an alkali based toxin called podophyllin. All other parts of the plant (including unripe fruit) are toxic. ![]() When the flower is pollinated the plant will produce a single large yellow berry that can be from 1 to 2 inches in diameter. ![]() A single white flower which grows from the point where the stem splits in two. Mature plants produce a pair of leaves that grow from a single stem. Immature plants will only produce one leaf and will not flower. Mayapple ( Podophyllum peltatum) produce large white flowers that are hidden under their large umbrella-like leaves. This species thrives in a variety of habitat types ranging from wet to dry and sun to shade. Like those species, the white flowers of Canada Mayflower have long stamen, making each individual flower look like a 1950’s Atomic Age art object.Īs the name implies, Canada Mayflower typically first blooms in the month of May and extends into June. The white flowers of Canada Mayflower bear a superficial resemblance to those of Foamflower ( see Part II) or Baneberry (see below). Instead this species only grows three to six inches tall and bears only one or two (rarely three) leaves. ![]() This species bridges the gap between late spring and summer look for it to flower between May and July.Ĭanada Mayflower ( Maianthemum canadense), sometimes known as False Lily-of-the-valley, does not have the long arching stems of the previous two members of its family. stellatum, growing in a variety of wooded habitats. The habitat requirements are similar to those of M. After pollination, the flowers are replaced with tiny berries that ripen to a bright red. While Starry False Solomon’s Seal bears only a handful of blooms, Feathery False Solomon’s Seal ( Maianthemum racemosum) has dozens of tiny (1/8 inch) blooms arranges in a 3 to 5 inch long spike. In Central Michigan, Starry False Solomon’s Seal lives in a variety of shaded and partially-shaded habitats with moist to wet soil including woodlands, woodland edges, floodplains, and swamps. Later in the year the blooms are replaced by green berries with purple stripes that eventually turn reddish-purple as they ripen. Starry False Solomon’s Seal ( Mainthemum stellatum) has flowers that are about 1/3 inch across and have six narrow white petals. All three can be distinguished from true Solomon’s Seal plants by having flowers at the end of the stem rather than hanging below the stem from the leaf axils. The next three species bear a resemblance to Downy Solomon’s Seal but are not closely related to that species. Look for the flowers of this species in May or June. The pale green to white flowers grow from the leaf axils (the place where the leaf attaches to the stem) and are arranged either individually or in groups of two to three. The tubular flowers of Downy Solomon ‘s Seal dangle beneath the plant’s arching stem. The species is often found growing on slopes. Look for Jack-in-the-pulpit to bloom between April and June.ĭowny Solomon’s Seal ( Polygonataum pubescencs) grows in moist woodland habitats, especially beech-sugar maple forests, and shrub thickets. Because of its three part leaves, this plant is sometimes incorrectly identified as Poison Ivy. The triphyllum in its Latin binomial mean “three-leaved”. Later in the year, the spadix and spathe will be replaced by a cylinder of green berries that will ripen to a bright red. With its pair of three part leaves and a hooded green or purple flower composed of a pale green spadix ( the jack) encased and topped by a spathe ( the pulpit) is easily recognizable. Most people who spend a lot of time in the woods are familiar with the Jack-in-the-pulpit ( Arisaema triphyllum). In Part II we moved a little further into the season and featured an additional fifteen species. In Part I we discussed the reasons behind our diversity of wildflower species and highlighted fifteen of the earliest bloomers. This is the third and final article of our series highlighting the spring wildflowers of Central Michigan.
