Nippon Daisies

So, we bought these daisies, and planted them in the bed in the front yard.  And they grew and grew all summer, and crowded out the whole right corner of the bed, but never produced any flowers. I was getting a little exasperated with all of the vegetative growth. And then the buds formed.  And now we have a profusion of lovely yellow and white daisies in the front yard. Didn't read the directions.  Nippon daisies (Nipponantheum nipponicum Franch. ex Maxim Kitam) always bloom in the early Fall. [NOTE: I still have a lot to learn about cultivated plants].
