Detailed Information

Flower: Flower shape: 6-petals

[photo of flower] Hanging  yellow flower 1 to 2 inches long with 6 droopy, narrow petals (tepals) that are somewhat twisted; 1 to a few flowers per stem. There are 6 long stamens that are hidden by the petals.

Leaves and stem: Leaf attachment: alternate Leaf type: simple

[photo of leaves] Leaves are up to 6 inches long and 2 inches wide with pointed tips; the base of the leaf is round and completely surrounds the main stem (perfoliate). There are several distinct veins running parallel to the main central vein, the leaf edges are often rolled under, and there are fine white hairs along the veins on the underside. Attachment is alternate. Stems are smooth and light green; a plant often has multiple stems, growing in a clump.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a 3-sectioned capsule roughly shaped like an inverted pyramid with rounded corners. Each cell contains several seeds.


Large-flowered Bellwort is easy to ID from the twisted flower petals and perfoliate leaves. Formerly in the Liliaceae (Lily) family, Uvularia has been reassigned to Colchicaceae (Autumn-crocus).

I just discovered, May 18, a new growth of large-flowered bellwort in the campus woods of Northwestern College in Roseville. These, along with new growth of Trillium, are evident since the removal of the buckthorn canopy in the woods. Both have "returned" to the woods after years of "hiding."

Uvularia grandiflora (Large-flowered Bellwort) now blooming in the Mississippi River gorge just a block from our house in the Seward neighborhood. Just lovely.

After many years of Buckthorn eradication, I have found really nice colonies now thriving in my woods. I found that seed collection can be tricky as the pods split open all at once and fling the seeds.

There are many of these in the forested areas around my home.

We live on the bluff over looking the Mississippi River valley and just found these flowers in an on a North slope where we also cleared a bunch of Buckthorn two years ago. Very pretty and seem to do well both on the edge of the woods and also 50 feet into the woods.

The bellwort are blooming in profusion in the marshy woods to the south west of Cass Lake, MN. Beautiful!

The storm that went through last night uprooted an oak tree in a wooded area of our property, near the base of the tree was a group of large-flowered bellwort along with a few trillium. What a thrill it was to see them. I have been thinking about trying to grow trillium in that area but wasn't sure if they wood grow there. I guess I have my answer!

we discovered these growing along the north side of our house (under an oak canopy). There are 2 large clusters of them. One clump is starting to cover jack in the pulpits, so we may try to move that clump. We'll leave the other clump undisturbed.

Have 3 large clumps of this in my back yard in the gardens. It is one of the first things that blooms in my yard every spring.

Discovered Ulvularia grandiflora for first time this growning season on April 23, 2012. Was happy to identify using this site. It's located in a two-year old hosta bed under a canopy of oak trees, which is adjacent to a wetland. The site also contains two types of Solomon Seal and other natives we are trying to identify. We are liking the natural look but are in a quandry. The hosta bed is named "The Pantry" so every plant chosen relates to food or pantry accessories.

While hiking and taking photos at Lake Maria state park I came across dozens of these Bellwort flowers. The twisting tepals are quite charming making for an interesting flower.

These softly twisted petals are intriguing to look at. Such a softly stated flower. Grows all over our wooded hillsides.

I live on the south end of Maplewood State Park and have many growing in the woods. I also get Jack in the pulpit and many others I am researching. So beautiful!

I was out hiking on the Suomi Hills Semi-Primitive Recreation trails, and I saw them everywhere! I took a picture and had to identify it here because it was so pretty!

Marilyn, "wild oats" is more often a common name for the related pale or sessile-leaf bellwort, Uvularia sessilifolia.

We have bunches of these! We moved here from Denver last fall and it is so much fun watching all the flowers popping up this spring! I can't wait to see what all we have and this site is a great reference! The previous owners planted so many perennials which I just love!

I started cleaning out the woods in my back yard this year. After I had a large area cleared out, these started showing up all over that area!

First time to see this plant! At the end of the creek trail at the old quarry area that must have burned recently (within months) we saw one clump. 9 May 2015.

Several were blooming in early May on a ridge at William Berry Park in the woods across the road from Lakewood Cemetery. They have a beautiful golden glow in the early morning light.

These are some of my favorite spring wildflowers and despite the recent cold temperatures, I was pleased to see that they are now in full bloom in the mature maple-basswood forest along the eastern shores of Leech Lake in the Chippewa National Forest.

These beauties are out in the thousands right now, it is just so stunning to see a huge sea of them in the woods!

Photographed what looked like a lone plant, close to the intersection of County Rd. 155 and County Rd. 92 along the NE side of Lake Waconia. Spotted the plant when walking along the Dakota Rail Trail. It was on the lake side of the trail. Photographed April 26, 2017.

5-6 plants of good size growing in the wooded area above the Ottertail River on my property. Just beautiful!!
