Gaillardia × grandiflora 'Bargaispinyel' SPINTOP™ YELLOW TOUCH blanket flower

Gaillardia

The genus Gaillardia belongs to the daisy family and comprises roughly a dozen species distributed from Canada to northern Mexico, landscapes where scorching summers alternate with cool nights and where plants have had to learn to survive wind, drought and fire. The first botanical descriptions date back to 18th and the genus is named after the French patron of botany Antoine René Gaillard de Charentonneau (1720–1799), who supported Parisian naturalists at a time when North America was becoming a new botanical Eldorado. Blanket flowers reached European gardens quickly thanks to their tireless willingness to bloom and their colours, which during the Victorian fascination with exotic plants looked like small suns carried from the fires of the prairie. Interestingly, some late Pleistocene fossil finds suggest that the ancestors of today’s blanket flowers also grew in cooler regions, which helps explain their surprising hardiness despite their warm looking appearance. Within the genus there is a degree of nomenclatural confusion between G. aristata and G. pulchella, as they hybridise readily and form transitional populations in the wild that botanists have renamed several times. Yet this very variability underpins the richness of today’s cultivars, which differ in colour, height and flowering period.

Hybrids within the genus Gaillardia arise most often from crosses between G. aristata and G. pulchella, the former contributing resilience, firm stems and cool‑tolerant traits, while the latter adds vivid colours, long flowering and a lighter, more open habit. This combination has produced the broad group of garden forms known as Gaillardia × grandiflora, which vary in colour, height and growth rate. Most hybrids reach 30 to 60 cm and show natural variability, as they readily revert to characteristics of both parents. A mild degree of heterosis means that in their first year after planting they tend to be particularly vigorous and floriferous, while in subsequent seasons their growth naturally settles. The history of these hybrids reaches back to the nineteenth century, when the first garden forms appeared in Europe, and modern breeding continues in the United States and Europe, especially in programmes focused on compact habit, early flowering and striking bicolour combinations. This natural variability and long breeding tradition underpin the diversity of today’s hybrid blanket flowers, which rank among the most rewarding summer perennials for sunny gardens.
