Gattinger's Prairie Clover, Purpletassels, Purple Tassels - Dalea gattingeri
|
Dalea gattingeri - Gattinger's Prairie Clover, Purpletassels, Purple Tassels. Dalea - the Prairie Clovers - is a fairly large genus with around 165 species, mostly of dry area in the Americas. There are more species in Mexico than in the United States, but there are over 60 species in the United States. Since they are found in dry areas it is to be expected that more species are found in the middle and southwestern parts of the United States than in the southeast, but Gattinger's Prairie Clover, Dalea gattingeri, is one of about a dozen found in the southeast. It is more common in middle Tennessee than in the other parts of its range - a few counties in East Tennessee, a few in Georgia, a few in Alabama, and 1 county each in Arkansas and Missouri. It blooms from May through August in limestone glades and other barrens that spend much of the year very dry.
Dalea purpurea is a similar species with a much wider distribution, as far east as Indiana south to middle Tennessee and northwest Georgia; much more widespread in the great plains states. Some differentiating characteristics are noted below in the descriptions accompanying the photographs.
Found in: AL, AR, GA, MO, TN

| Site: Chickamauga Battlefield Cedar Glade, Catoosa County, Ga Date: 2014-May-21 | Photographer: Gerald C. Williamson Nikon D7000 Tamron SP 90MM f/2.8 AF Macro | Both Dalea gattingeri and Dalea purpurea have a somewhat compact floral head initially, made up of many purplish flowers. Those of D. gattingeri will lengthen notably as the flowers open from bottom to top, while that of D. purpurea will remain more compact. | |
