Star-of-Bethlehem (Ornithogalum umbellatum) has a number of local names, such as Betty-go-to-bed-at-noon, morning star and nap-at-noon, which suggest that its flowers open in the morning but close at about mid-day.  And, indeed, another name is sleepy Dick, ‘from the early closing of its flowers’.  But star-of-Bethlehem flowers appear to remain open in the afternoon, as shown in this photograph taken on Tooting Common, London Borough of Wandsworth, at about 4.00 p.m. on 29 April 2017.
