About the genus

Gaillardia is a genus of flowering plants in the family Asteraceae, native to North and South America. It was named after Maître Gaillard de Charentonneau, an 18th-century French magistrate who was an enthusiastic botanist. The common name may refer to the resemblance of the inflorescence to the brightly patterned blankets made by Native Americans, or to the ability of wild taxa to blanket the ground with colonies.

In the garden

Gaillardia × grandiflora is a perennial member of the Asteraceae, recorded as native to New South Wales. It produces blooms through the summer months, with a reliable flowering span from June to September, making it a useful choice for sustained colour during the main growing season. Give it a sunny position in well-drained ground; the species accepts soils from dry to medium moisture and does not tolerate waterlogging. Its H5 rating translates to being hardy in most of the UK when planted in open ground, so it will survive typical winter conditions in those areas provided drainage is good. Use Gaillardia × grandiflora in mixed borders, planted in containers, or in rock gardens where free-draining conditions can be maintained. Position plants where their season-long flowering can be seen through the summer months and avoid heavy clay that holds water. The June-to-September flowering window is its chief asset for providing continuous summer colour in the garden.
