Helianthus 'Happy Days' features numerous double yellow flowers on 3-4 foot tall plants. These plants bloom continuously from June through September. It looks great with Rudbeckia 'Little Henry.'

In going through the Heleniums in the Database, I found a glaring error. On page 6 of Helenium entries, there is: Dwarf Perennial Sunflower (Helianthus 'Happy Days'). I thought, How could they possibly put a Helianthus in with all the Heleniums? Just yesterday I submitted two photos in the Helianthus category of 'Happy Days'.
So I returned back to this category, and there it was: "Also Sold As 'Helenium Happy Days' ".

One can certainly find strange entries in the Database.
