Oenothera pallida (pale evening primrose)
Delicate white flowers can bloom all summer
Pink drooping buds open in the evening to show off delicate white flowers that bloom for a day before fading to pink. This plant typically grows in sand dunes, spreading by rhizomes to move around a little from one year to the next. It can tolerate some extra water but does very well in dry sandy soil.
Water: low to moderate
