Detailed Information

Flower: 5-petals round spike

[photo of flowers] Flowers are in rounded pink to purple heads ½ to ¾ inch long, tightly packed in a spike-like cluster up to 10 inches long. Heads are made up of 3 to 8 star-shaped disk flowers each with 2 long curving styles emerging from the center. The bracts are pressed flat against the head or only slightly spreading, broad at the base, sharply pointed at the tip, with long white hairs around the edges. Bract color is green to purplish. One plant may have multiple stems, each with a single spike that blooms from the top down.

Leaves and stem: alternate simple

[photo of leaves] Leaves are very narrow and grass-like, up to 4 inches long and ¼ inch wide near the base of the plant, becoming progressively smaller as they ascend the stem. Leaves are covered in dots of resin, have short white hairs around the edges, are densely packed on the stem and tend to point upward but may be more spiraling at the base of the plant. The main stem is hairless.

Fruit:

[photo of fruit] Fruit is a small dark seed with a tuft of light brown hair to carry it off in the wind.

Notes:

Dotted Blazing Star tends to grow in clumps. There are 5 species of Blazing Star in Minnesota. A good way to tell them apart is by the shape of the bracts, which is unique for each species. Dotted Blazing Star has relatively large bracts that are pressed flat against the flower head or only slightly spreading, with long white hairs around the edges.
