More from RHS Harlow Carr Gardens near Harrogate: I think the big white flowers above are Cosmos. One of them was providing a lovely hammock for a pretty pale green butterfly, which may have been a green-veined white? The pink flower below is a Cosmos too. They were growing in an exuberant planting of mixed annuals, which seemed to have both wild and cultivated species.
Sunflowers are always a joy and I liked this variety with two-toned petals.
Another plant that makes a bold statement is Acanthus spinosus, commonly known as bear's breeches. It's wonderfully sculptural with its long spikes of hooded purple and white flowers.
