Leucanthemum maximum, known as max chrysanthemum and Shasta daisy,[1] is a species of flowering plant in the aster family.

Range

[edit]

It is native to France and Spain but it can be found growing wild in other parts of the world as an introduced species and sometimes a garden escapee.

Description

[edit]

It is a rhizomatous perennial herb growing 30 to 70 centimeters tall with many large serrated leaves around the base of the stem on winged petioles. There are smaller lance-shaped leaves alternately arranged along the stem. The inflorescence is generally a large, solitary flower head which may exceed 8 centimeters in diameter. It has a fringe of 20 to 30 white ray florets around a center of many densely packed yellow disc florets. The fruit is a small ribbed achene without a pappus.

Taxonomy

[edit]

This species is one of the wild chrysanthemums Luther Burbank crossed to produce the popular garden hybrid known as the Shasta daisy, Leucanthemum × superbum.[2][3]
