I believe the shasta daisies are whati have once they start growong have them a very long time

Hello Leasa, I planted Montauck Daisy's last year, they are in full bloom now and will keep blooming until we get a very hard frost. They are gorgeous! The foliage is a very rich green so it looks pretty while growing throughout the summer.
