    I grew 'Professor Einstein' for 10+ years before finally removing it; no matter what sun exposure I provided for it, the weak stems would never hold the blooms upright. The first rain after the flowers opened always bent them flat to the ground.

    This variety caught our attention from across the daffodil pavilion at the Keukenhoff in 2009. Large blooms have good substance and are long lasting in the vase. I love including this one in bouquets, as the bright orange centers just show off really well against the usual daffodil white and yellow tones.
