Calystegia sepium
It is a perennial, herbaceous liana growing to a height of 5-30 m tall with twining stems. The leaves are entire or three-lobed, 5-15 cm long, with a 5-20 cm long stem. The flowers are fragrant, white or pink, and large, 8-14 cm diameter. The flowers open quickly in the evening and last through the night, remaining open until touched by the morning sun. On overcast days, the blossoms may remain open for longer.
The large bracts covering the base of the flowers is characteristic of Calystegia sepium which is very cold hardy...Ipomoea alba rarely gets to flower in Canada and realistically wouldn't set seed...
