I am trying to identify an annual that is referred to as Macheyka in Polish. Popular flower in Poland. It's blooms open at dusk with a very fragrant scent. Grows 1-2 ft high - may require trellis or some sort of support. Looks like grass when the blooms are closed. Flowers are blue or a shade between blue and lavender. Tiny black seeds/pollen. All my aunt remembers is that she found a packet of seed for this flower last year in central Canada and there was a reference to "Fragrance of Summer". Please help me identify this plant. Thank you!
