Detailed Information

Flower: 7+petals flat

[photo of flowers] Up to 20 flowers are in an open cluster at the top of the plant, and on stems branching from the leaf axils near the top of the plant. Individual flowers are yellow, about 1 inch across, and resemble dandelions.

Leaves and stem: alternate basal lobed simple

[photo of lower leaves] Leaves change shape as they ascend the stem. There is a rosette of basal leaves, each up to 6 inches long and 1 inch wide, coarsely toothed with a pointed tip and short leaf stem. Leaves on the lower part of the stem are more irregularly toothed or divided with sharply pointed lobes and curled edges.

[photo of upper leaves] The stem leaves quickly lose this shape and progressively become smaller and very narrow, toothless, with no leaf stem. Leaves near the top of the plant are less than ¼ inch wide. The main stem is hairy and ridged.

I saw these near the Marina on the Reservation near the National Monument.

We have a lot of these, both by the water and in the forest along the path from the cabin.

On second glance, I think what we have in abundance is Hairy Hawkweed. They have a leafless 1' stem and a cluster of just-blossoming flowers.

What you probably really have is a different weedy hawkweed, possibly king devil, Hieracium piloselloides, or meadow hawkweed, Hieracium caespitosum. Hairy hawkweed, Hieracium longipilum is an uncommon native, taller than 1 foot with very long hairs on the leaves and stems. If you have some images you can post them on our Facebook page and we'll see if we can give you a positive ID.
