About Erigeron karvinskianus DC.
Erigeron karvinskianus DC. is a vigorous, spreading perennial plant that grows from woody rhizomes and reaches a maximum height of 15 cm (5.9 in). Its leaves grow along the stem, and basal leaves die off as the plant produces its flowering stalk. Leaves are sometimes slightly toothed or lobed near their tips. The inflorescences bear one or more flower heads, each about 1 cm (0.4 inches) wide. Each flower head has golden yellow disc florets at the center, surrounded by a fringe of up to 80 white to pinkish ray florets. This species is native to most of Mexico, Central America, Colombia, and Venezuela. It is naturalized in many other regions, including parts of Africa and Europe, Australia, Hong Kong, Chile, the west coast of the United States, and New Zealand; in New Zealand, it is a weed that interferes with native forest restoration. Erigeron karvinskianus is cultivated for its daisy-like blooms, and is often confused with the closely related common daisy Bellis perennis. It is frequently grown in crevices in walls or paving, where it spreads rapidly to form a carpet of flowers. It has been awarded the Royal Horticultural Society's Award of Garden Merit. It was used to colonize the concrete terraces of Estadio Azteca, the Mexico City football stadium built for the 1970 World Cup.
