What's Bloomin'?


Time for the annual Rally Weed “What’s Bloomin’ in the Black Hills?”!

For those of you visiting the Black Hills in the coming weeks, you could see many of the season’s showiest blooms along the roadsides.

Unfortunately most of the highly visible roadside flowers are of the weedy variety.  Several species of non-native or noxious weeds can be seen as swaths of color.  Generally the yellow along roadsides is sweetclover (Melilotus officinalis).  The swaths of white are generally oxeye daisy (Leucanthemum vulgare).  Other weedy species can be seen in smaller patches in disturbed areas such as roadside.  These include nodding plumeless thistle (Carduus nutans), Canada thistle (Cirsium arvense), common St. Johnswort (Hypericum perforatum), crownvetch (Securigera varia), and common mullein (Verbascum thapsus).

If you are in Spearfish Canyon, the blue flowers growing in and along the water are true forget-me-nots (Myosotis scorpioides).  Elsewhere in the Black Hills you can see seas of purple flowers.  The most common purple bloom is beebalm (Monarda fistulosa).  One of the showiest flowers currently blooming is blanket flower (Gaillardia aristata).  It is not very common, but is very noticeable.

Several yellow flowers are currently showing curlycup gumweed (Grindelia squarrosa), fringed loosestrife (Lysimachia ciliata), seep monkeyflower (Mimulus guttatus), cutleaf coneflower (Rudbeckia laciniata), and blackeyed Susan (Rudbeckia hirta).

White flowers that can be seen right now include common yarrow (Achillea millefolium), western pearly everlasting (Anaphalis margaritacea), broadleaf enchanter’s nightshade (Circaea lutetiana), white avens (Geum canadense), American licorice (Glycyrrhiza lepidota), common snowberry (Symphoricarpos occidentalis), and white clover (Trifolium repens).

Other purple flowers currently in bloom include harebell (Campanula rotundifolia), blacksamson echinacea (Echinacea angustifolia), Richardson’s geranium (Geranium richardsonii), alfalfa (Medicago sativa), wild mint (Mentha arvensis), common self-heal (Prunella vulgaris), red clover (Trifolium pratense), and hoary verbena (Verbena stricta).

Hope that enjoy the color blooming in the Black Hills!
