Tradescantia or spiderwort. In the summer the flowers close around noon, but later in the year, or whenever the sun is less intense, they stay open all day. (The Tradescantia family of flowers is named after John Tradescant, the keeper of Gardens, Vines and Silkworms for king Charles I - en.wikipedia.org/wiki/John_Tradescant_the_Elder) .
