April Wildflowers in Bloom

Bloodroot

Fun Facts:

Named for its red juice, this flower is the only species in the genus Sanguinaria, and it grows only in North America. Native Americans used the juice of these plants as a paint and dye for fabrics. Ants are attracted to the flower’s seeds and help to spread them, but humans should be very careful–these lovely plants are poisonous!

Hot Spots

Cutleaf Toothwort

Fun Facts:

These delicate plants have a lovely fragrance, and you have to act fast to spot them: they have only a two-week blooming period before the leaves return to the trees above them and block their sunlight. They are a favorite food for mice!

Reference the Quest Map to help guide you to this flower.

Hot Spots

Dog Violet

Fun Facts:

Do you know how this plant got its name? It’s called a “dog” violet because it has no scent, unlike its cousin, the “Sweet” violet! That seems unfair for such a lovely flower. The different varieties of violet mate together very easily, so you are likely to see many hybrids.

Hot Spots

Dutchman’s Breeches

Fun Facts:

It’s easy to see how these distinctive white flowers got their name: they look just like small upside down pairs of pants! While commonly white, they sometimes also have pink flowers. While bumblebees love these plants, they are quite toxic. In fact, one of their common names is “Little Blue Staggers,” for the effect they have on unlucky cattle that graze on them!

Hot Spots

Harbinger of Spring

Fun Facts:

This tiny flower is one of the early blooms—a sure sign that spring is on the way! While common in the Indiana Dunes area, they are protected as state endangered plants in New York and Wisconsin. It’s also called a Salt and Pepper Plant because of its distinctive white and purple coloring, and it’s actually part of the carrot and parsley family!

Hot Spots

Meadow Buttercup

Fun Facts:

These flowers bring a lot of folklore with them! Known as “crazyweed,” legend has it that smelling the flower can cause insanity! It is also known as “blister plant” for the effect it has on the poor cattle unfortunate enough to graze on it!

Reference the Quest Map to help guide you to this flower.

Hot Spots

Meadow Cress

Fun Facts:

Another name for these European natives is the “cuckoo flower.” Some say it’s because they would bloom at the same time that cuckoo birds returned to Great Britain. They also attract a number of species of bees, including cuckoo bees! Their cup-shaped flowers have also earned them the name “Lady’s smock.” Legend has it that picking them is unlucky, so remember only to take pictures!

Hot Spots

Northern White Violet

Fun Facts:

This very small flower will require special attention to spot. Luckily, these lovely flowers have a long blooming season. They also emit a sweet fragrance and attract a number of pollinators–and people on the Dunes Flower Quest!

Reference the Quest Map to help guide you to this flower.

Hot Spots

Prairie Trillium

Fun Facts:

Look carefully for the three maroon petals of these native flowers. The flower of these plants is eventually replaced by a dark-colored berry. So not much to attract pollinators! Luckily, ants help to spread their seeds, and even deer that like to graze on them.

Reference the Quest Map to help guide you to this flower.

Hot Spots

Skunk Cabbage

Fun Facts:

These incredible plants emit an odor that gives them their name (Phew!), but that same odor also attracts the flies and insects it needs for pollination. Even more impressively, these plants generate their own heat, melting the snow around them as they begin to bloom in spring!

Reference the Quest Map to help guide you to this flower.

Hot Spots

Wood Anemone

Fun Facts:

With their slender stalks, these plants have also been called “wind flowers” for the way they move in the breeze. The flowers can be pink or white, and in spite of their beauty, are quite toxic. Wood Anemone is often confused with False Rue Anemone, which does not have a whorl of leaves under its flowers.

A Note on Invasive Wildflowers

The Indiana Dunes are home to so many beautiful wildflowers. Unfortunately, not all of them belong here. Over the years, non-native species have taken root in the region, crowding out native species that are crucial for supporting fragile ecosystems. The parks, non-profit organizations, and volunteers work diligently to restore these areas.

If you spot an invasive species, please leave it be: it takes careful oversight to remove these plants without damaging the area, and poison ivy, ticks, and sometimes even toxins from the plants themselves can be a hazard.

Gill Over the Ground

This plant has many names, including ground-ivy, creeping charlie, alehoof, catsfoot, field balm, and run-away-robin. It was even known as “ale ivy” because it was used in beer! It is a non-native, invasive plant in the U.S. And as anyone who’s had this in their yard might know, it has an extensive root system that crowds out other plants and makes it quite tough to pull!

Scilla

These blue-flowered plants are part of the lily family, and small patches have generally been found at the bases of trees at the Duneside Shelter in the Indiana Dunes State Park. These non-native plants were brought over from Europe as ornamental plants many years ago, and then spread from the manicured gardens where they began.

Small-Flower Crowfoot

These small flowers are part of the buttercup family, and are also commonly known as “kidneyleaf buttercups” because of the shape of the basal leaves on the long stalks at the base of the plant (not the stem). Their petals are some of the smallest of all the buttercups. Oh, and don’t let the name “buttercup”fool you: these plants are toxic!

Tips for Responsible Wildflower Viewing

As you explore the blooming beauty of the Indiana Dunes, please take a moment to help protect the delicate wildflower habitats.

Stay on marked trails to avoid trampling fragile plants and budding blooms.
Resist the urge to pick flowers—many species are fleeting, and leaving them ensures others can enjoy their beauty and pollinators can do their work.
If you’re tracking wildflowers, use a smartphone or notebook rather than tagging plants or leaving markers.
And as always, pack out everything you bring in. Practicing Leave No Trace helps keep the dunes vibrant and blooming for future springtime visitors.

Thanks for promising to Love + Protect the Indiana Dunes!
