What's Bloomin'?

As we move into late June, the array of wildflowers blooming across the Black Hills has shifted to species associated with mid-summer.  Along many of the highways, the spikes of white flowers of the soapweed yucca (Yucca glauca) as well as the purple of beardtongues (Penstemon sp.) are highly visible. 

In the higher elevations, some early season blooms, including pale agoseris (Agoseris glauca), textile onion (Allium textile), arrowleaf balsamroot (Balsamorhiza sagittata), scarlet beeblossom (Oenothera suffrutescens, formerly Gaura coccinea) and old man’s whiskers (Geum triflorum), although this species is in fruit across much of the Hills.

In lower, warmer places common yarrow (Achillea millefolium), bluebell bellflower (Campanula rotundifolia), sulphur paintbrush (Castilleja sulphurea), field chickweed (Cerastium arvense), wavyleaf thistle (Cirsium undulatum), northern bedstraw (Galium boreale), Richardson’s geranium (Geranium richardsonii), Richardson’s alumroot (Heuchera richardsonii), large breadroot (Pediomelum esculentum), spearleaf stonecrop (Sedum lanceolatum), American vetch (Vicia americana), American speedwell (Veronica americana), and heartleaf Alexander (Zizia aptera) are all blossoming.

Blooms on shrubs that are currently visible include wild rose (Rosa sp.) and American cranberrybush (Viburnum opulus var. americanum).  The chokecherries (Prunus virginiana) have moved on to the early fruiting stage.

Unfortunately, warmer weather means the introduced and invasive species are starting to bloom as well.  Currently houndstongue (Cynoglossum officinale), leafy spurge (Euphorbia esula), dames rocket (Hesperis matronalis), oxeye daisy (Leucanthemum vulgare), black medic (Medicago lupulina) and red clover (Trifolium pratense) are blooming.

The abundance of blossoms will shift as summer continues, so check back again to see What’s Bloomin’ in the Black Hills!
