Helenium Mardi Gras
Have a stand of underperforming Rudbeckia early bird gold that will be moving. It is placed behind a boxwood hedge that only gets 1.5 ft high and still the Rudbeckia barely peeks over the top. The spot gets sun till about 2pm and is a raised bed.
I wanted to plant Helenium in the spot and was thinking of Mardi Gras based on reviews. Behind it would be Double knockout rose shrub. I don't worry about flopping as it could lean on the boxwoods and I could also stake if needed. Only problem is would it get too tall for the spot?
