Answer: There are lots of flowers you could be talking about, many flowers have the daisy form and come in a wide variety of colors. You may be talking about an aster, there are several varieties that look like a blue daisy. You don't by any chance know the botanical name of the plant she saw do you? If she saw it at Longwood Gardens they surely had it listed with the plant. I'm not sure where this is but perhaps you could call them and get a botanical name so we can find exactly what she saw.
Meanwhile, Burpee sells 'Bluebird' Aster, a variety that looks like a blue daisy. To reach Burpee call 1-800-888-1447.
