The Evening Lychnis (White Champion, White Cockle) (lychnis alba)
The Evening Lychnis is not native to America but now is quite common and considered to some to be a weed. It is a perennial and once established it can be very difficult to eradicate. Its white flowers attract moths which carry out pollination. The leaves of the Evening Lychnis are clasping and ovate. The flower consists of 5 deeply cleft petals and below it is an inflated sac or calyx. This calyx is coated with a sticky substance so to prevent the ants from getting at the sweets of the flower intended for only the moths.
