Detailed Information

Flower: Flower shape: 6-petals

[photo of flower] Flower is about 1 inch long and hangs down on a slender stalk. There are 6 pale yellow or cream colored petals that curve out slightly at the tip end. The petals are not fused, as most bell-shaped flowers are. A plant usually has a single flower, but occasionally has 2.

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

[photo of leaves] In early spring leaves may look grass-like, up to 3 inches long and 1 inch wide, tapering to a point at both ends, with no stalk. The edges are smooth and often rolled up but flatten and spread out with maturity. Distinct parallel veins are easily seen on the underside of the leaf. The main stem forks into 2 branches near the top of the plant, with a few leaves on each branch. The main stem is sheathed (see photo below) on the lower 1/3 of the plant, and tends to zig-zag between the alternately attached leaves..

Fruit:

[photo of fruit] Fruit is a ¾ to 1¼ inch long capsule, generally oval to round with an abrupt point at the tip and tapering at the base to a short stalk. There are 3 distinct winged edges around the capsule.

Notes:

It's easy to miss seeing the flower because it's a short plant and the flower may be hidden under the leaves. Large-flowered Bellwort (Uvularia grandiflora) also grows in the same habit at the same time of year, but has brighter yellow flowers with twisted petals, and leaves that surround the stem (perfoliate). Formerly in the Liliaceae (Lily) family, Uvularia has been reassigned to Colchicaceae (Autumn-crocus).

i found these on our property in bovey minnesota. they do not normally grow in that area and never have on that property. our dog died last summer and this spring these flowers sprouted in a 10-15 foot radius around her grave close to mothers day. our daughter said they should be renamed roses because of the special circumstance surrounding their growth.
