About
Achillea grandifolia 'Friv.' is a herbaceous perennial that typically grows between 40 and 100 centimeters tall. It features grey-green stems that become woody at the base. The leaves are adorned with fine silvery hairs on both surfaces, lending them a distinctive grey-green hue. These leaves range from 7 to 20 centimeters in length and 5 to 10 centimeters in width, displaying a shape that varies from flat and lanceolate to broadly ovate. They are deeply pinnatifid or pinnatisect with 4 to 6, occasionally 8, pairs of cuneate-lanceolate segments. In early summer, this plant produces dense corymbs measuring 5 to 20 centimeters across, each composed of 50 to 250 flower heads. Each head typically features 4 to 5 white ray florets. Care should be taken to distinguish this species from Tanacetum macrophyllum.
About the genus
