Detailed Information

Flower: Flower shape: 7+petals

[photo of flowers] A single flower 1 to 2 inches across is at the end of a long, mostly naked flower stalk at the top of the stem, sometimes also arising from uppermost leaf axils. Flowers have 15 to 35 white petals (ray flowers) and a golden yellow button shaped center disk, up to ¾ inch across. The bracts surrounding the base of the flower are in 2 to 4 layers and are green with dark purplish-brown edging.

Leaves and stem: Leaf attachment: alternate Leaf attachment: basal Leaf type: lobed Leaf type: simple

[photo of stem and mid-stem leaves] Basal and lowest stem leaves are up to 5 inches long and ¾ inch wide, generally spoon to spatula shaped with narrow lobes or large teeth and a long stalk. Leaves become smaller, more linear-oblong, and stalkless as they ascend the stem. Stems are multiple from the base (up to 40), seldom branched, angled or furrowed, and mostly hairless. Large colonies can form from creeping rhizomes.

Fruit: Fruit type: seed without plume

The center disk becomes a head of dry, brown, ribbed seeds that lack tufts of hair. Each flower produces up to 200 seeds.

Notes:

Ox-eye Daisy, formerly known as Chrysanthemum leucanthemum, is easily recognizable, commonly found in gardens all across the US. It was brought over from Europe in the 1800s, escaped into the wild and has become an aggressive, invasive breeder, often seen along roadsides, trail edges, in old fields and other disturbed soils. The leaves easily distinguish this species from others with similar flowers. Leucanthemum vulgare is one of the parents of Shasta Daisy, a popular garden plant that is reputed to lack the invasive tendency of its parent. Time will tell.
