Masses of yellow daisies with brown centers make this a late-season garden standout. We bought it last year as a perennial, but learned later that it usually behaves as a biennial. I'm not sure if the plant pictured was a returning remnant of the original plant, or a quick-to-bloom seedling. Either way, we hope to establish a permanent stand in our garden.

The leaf way at the bottom shows the reason for the species name - the basal leaves have three lobes

Another year, a big crop of seedlings - color explosion!

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
