Field Notes

Description:

Leavenworth’s eryngo is a prickly, 20-40 in. annual with a leafy stem, broadly branched in the upper portion. Almost the entire plant has some shade of purple. Flowers are minute, purple, and mingled with small, spiny bracts in an elongated, terminal, head-like cluster. These are subtended by conspicuous spiny-tipped bracts. The leaves are deeply lobed, each segment edged and tipped with stiff spines. A tuft of small, rigid, spiny leaves grows out of the top of the flower head. It is desirable to wear a thick pair of gloves if one cuts the flowers.

Habitat:

dry rocky prairies, roadside fields, open woodlands, and waste areas

Notes:

The eryngos are not true thistles and are often confused with thistles, due to similarity in both appearance and habitat preference. Splashing fields a brilliant purple, it provides an excellent source for late summer and early fall color.
