Gaillardia aristata Pursh
Common Name: COMMON BLANKET-FLOWER
Coefficient of Conservatism: *
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Ad P-Forb

Native west of the Great Lakes, here escaped to roadsides, fields, fencerows, vicinity of old gardens, and disturbed sites. First collected in Oakland Co. in 1916.

A tetraploid hybrid between this species and G. pulchella arose in cultivation in Belgium and was named G. ×grandiflora Van Houtte. It is now grown in preference to the less vigorous G. aristata (to which it will key here). Some collections mapped as G. aristata may in fact be the hybrid and we have clear-cut collections of the hybrid at least from disturbed sites in Emmet and Schoolcraft Cos.; on these, the tip of the rays is barely 2-toothed or shallowly 2–3-lobed, the lobes less than 20% of the total length of the ray. Whether the small sample available is representative is uncertain. In our G. aristata, the lobes are more numerous and more than 20% of the ray.
