Parthenium integrifolium

The Wild quinine or American feverfew from the prairies of N America makes a clump forming hardy perennial bearing flat-topped clusters of densely packed unusual white flowers akin to Anaphalis atop branched stems to 1.2m above bold oval toothed foliage in summer. This has a good degree of heat and drought tolerance and flowers over a long period, potentially from June to September.
