After a long, cold winter in Michigan, nothing is more refreshing and exciting than seeing the first buds of flowers peeking from the newly thawed ground. The spring and summer months are full of intense beauty and color when all of the wildflowers are in bloom, showing off their amazing color displays. Michigan offers a wide variety of spring wildflowers, many of which are located only in specific regions. MNA sanctuaries protect many of these rare and beautiful flowers, preserving their beauty for visitors to enjoy for generations to come.

The trillium has been used to symbolize purity, simplicity, elegance and beauty for years. Every spring, the woods of Michigan are filled with the beauty that the trillium has to offer. Trillium typically thrives in moist, woodland settings where rich, acidic soil is present. At first glance trillium appear to have unbranched stems, but they actually produce no true leaves or stems above ground. Instead, the stem is an extension of the horizontal rhizome (a stem that grows underground continuously and sends out shoots and roots above the ground) and produces small bracts that look like leaves. These flowers have three large petals that can be found in a variety of colors. Their seeds are distributed by ants that feed on the oil-rich structure, called elaiosome, that is found on the seeds.
Four trillium species are protected in Michigan. The state lists toadshade, prairie trillium and snow trillium as threatened and painted trillium as endangered. MNA sanctuaries protect several trillium species, such as drooping trillium, red trillium, painted trillium, prairie trillium and toadshade. The biggest sources of threat are animal grazing and urban development. Deer are known to feed on the flower which leads to diminishing populations. Several MNA sanctuaries are home to this striking flower.
Dwarf lake iris

This beautiful flower grows nowhere else in the world but in the Great Lakes Region, making it a rare sight to see and a favorite among visitors. This unique flower is also Michigan’s state wildflower. Most of the population lies within Michigan and is heavily concentrated along the northern Great Lakes shoreline, but they are also found in Wisconsin and Ontario. They grow on sand or thin soil over limestone rich gravel or bedrock. The dwarf lake iris tolerates the full sun to near complete shade, but flowers mostly in semi open habitat. These plants bloom from Mid-May to early June and are threatened in the state of Michigan.
The dwarf lake iris can be distinguished by its tiny size and thin, yellow rhizomes or underground stems. The slender rhizomes produce fans of flattened leaves that can reach a height of six inches. The light green leaves are no more than half an inch wide. The flowers of the dwarf lake iris are a deep, dark blue that are produced singly on short stems. These flowers grow in dense bunches that form a brilliant blue carpet.

The ram’s head orchid, or ram’s head lady’s slipper, is a species of special concern in the state of Michigan. They can be found through northern lower Michigan and across the Upper Peninsula. These plants can be characterized by three to five bluish-green elliptic leaves that sprout along the stem of the flower in a spiral arrangement. They produce a small, terminal flower that has a pouched lower lip. The petals of the flower are similar to the leaves in shape, but are wavy. The flower has purple or brown sepals, which are often streaked with green. The pouch of the lip is white and marked with purple, crimson or green net-like veins and the mouth of the pouch is hairy. These flowers only grow to be about 30 centimeters tall. The ram’s head orchid is appreciated for its delicate beauty and pleasant fragrance. It is also one of the most distinctive of the lady’s slipper orchids.
The ram’s head orchid grows in confined cool, moist wetlands and coniferous forests. They also have a preference for moist, mossy bogs. They are very long-lived and can take 10 to 16 years to reach maturity. Flowering occurs from mid-May to mid-June when the flowers are pollinated by bees, insects and birds that aid in transporting the seeds to various locations.

Virginia bluebells are ephemeral wildflowers; the blooming period occurs from mid-to late spring and lasts about three weeks. The central stem, which can reach a height up to three feet, is hairless and usually light green in color. The leaves can reach seven inches in length and are light green with a soft, floppy texture. The Virginia bluebell flowers are arranged in clusters and the tubular baby blue flowers flare at the mouth, displaying their bright yellow stamen. The flower clusters hang from arching stalks at the tips of the branches. The flower is tubular at the base and forms a bell shape towards the outer rim. They bloom from pink bulbs and when the flowers are ready for pollination, the plant increases its alkalinity to change the pink pigmentation to blue, which is a much more attractive color to various pollinators, such as butterflies and bees.This striking spring flower is a very popular species to be seen at MNA sanctuaries.
In Michigan, bluebells grow in southern floodplain forests and rich ravines. Just over ten state localities for them have been documented in Michigan. The vast majority occur in Kent and Ottawa counties.

The evening primrose is a vivid flower when it blooms in late spring. This species is a perennial with quite a short bloom period. Its flowers can be seen in May and June.
These plants produce stunning bright yellow blossoms that stand out among others. Evening primrose flowers open in clusters at the top of the plant. each flower has four petals and a slightly glossy look. The flowers themselves only last for a day when they first open in the evening. After they dazzle viewers with their brilliant yellow petals, they turn a salmon color before they die and fall off the plant. The flowers of the evening primrose have a large X- shaped pistil which projects beyond the stamens. The leaves of this plant are narrow and lance-shaped. They can reach up to six inches in length and have a silvery sheen on the surface of their petals due to short hairs that cover them. This wildflower grows close to the ground and sprawls out in areas of full sun.
Visitors will have the opportunity to see some of these spectacular species of wildflowers throughout the spring at MNA sanctuaries, so be on the lookout for some of these brilliant flowers! You can enjoy a whole weekend of wildflowers on our Wildflower Weekend Getaway, or take a guided hike during the Wildflower Walkabout series.
