OXEYE DAISY — Chrysanthemum leucanthemum L.

Asteraceae — (Sunflower family)

Oxeye daisy, a perennial ornamental, has escaped to become a weed problem in some areas, generally on road sides, waste places and meadows.
 
First year leaves are spoon shaped dark green, grow as a low round mound, with a light green leaf stalk and very toothed edges.  Second year is the same with numerous stems.  Long narrow leaves grow right against the stem, becoming fewer and smaller as they grow upwards.

The stiff, fibrous branching stems are 10 to 24 inches tall, somewhat hairy and may be reddish.  1½" white flowers with yellow centers top each stem and mature to produce about 200 seeds each.  The plant produces flowers all the summer season.  Wind or transported plants spread the seeds. 
Perennial roots grow several inches deep and produce more plants on short creeping rhizomes.

This plant irritates the hands of gardeners.  It also irritates the legs, face, and mouths of grazing animals such that animals avoid grazing on areas where the daisy is.  Since no grazing occurs the plant becomes an infestation in a year or so.

Often transplanted as an ornamental, oxeye daisy is an erect rhizomatous perennial, ten to twenty-four inches tall, glabrous to sparsely hairy. Leaves progressively reduce in size upward on stem. Basal and lower stem leaves are oblanceolate to narrowly obovate, two to five inches long including the petiole, margin crenate to lobed or parted. Upper leaves become sessile and merely toothed. Its white flower heads with yellow centers are solitary at the ends of branches, about one and a half inches long. Fruits have about ten ribs.

Oxeye daisy is a native of Eurasia and has escaped cultivation. It can be found in meadows, roadsides and waste places. Persons picking the “pretty” flowers easily spread Oxeye Daisy plants. Wildlife and livestock do not like to graze or walk through an area infested with Oxeye daisy since the plants irritate their legs and faces. Thus oxeye daisy can directly reduce wildlife habitat. Flowering occurs from June through August.

Growth Habit: Perennial, erect to 2` tall.

Leaves: Lower leaves – lance-shaped, 2 to 5" long including short stalk, margins lobed or deeply parted. Upper leaves – lance-shaped, attached directly to stem, margins toothed.

Stems: Numerous from root crown, terminating in flowers.

Flower: Solitary, 1½" wide, numerous white petals and a yellow center. Flowers June to August.

Roots: Fibrous.

Seeds: Straw colored, 1/8" long.

Other: Eurasian introduction, escaped from cultivation.
