Now let’s look at some specific perennial pairings that allow red and yellow flowers to play off one another:

• Try combining yellow yarrow (Achillea) and red bee balm (Monarda) for a long bloom sequence.
• Partner the feathery yellow blooms of tickseed (Coreopsis) with the bold red Oriental poppies for contrast.
• Underplant the towering red spikes of Lobelia ‘Fan Scarlet’ with a yellow and green variegated hosta.
