Arctanthemum integrifolium, the entire-leaved daisy, is a subarctic species of plant in the sunflower family. It grows in Alaska, northern Canada, Peary Land in northern Greenland, and the East Chukotka region of eastern Russia.[2][3][4]

Description

Arctanthemum integrifolium is a perennial herb, rarely more than 12 cm (4.7 in) tall, with a woody underground caudex and a basal rosette of leaves. Each plant usually produces only one flower head, blooming in the summer, containing 11–19 white ray flowers surrounding 60–80 yellow disc flowers.[5]

Distribution and habitat

This plant grows in alpine zones, found most typically on gravelly sites, arctic tundra, and exposed areas with low organic content, such as rock, sand, or gravel.[6] It does not thrive in areas near the sea or where otherwise exposed to salt spray.[6]
