32-36" tall x 24" wide (seed propagated). 'Brilliant' Oriental Poppy is a scarlet-orange flower made famous by New Mexico artist Georgia O'Keeffe's beautiful paintings from the 1930s. And no wonder: spring in Santa Fe brings with it drifts of Brilliant Oriental Poppies blooming all over town. Papaver orientale Brilliant will go dormant in summer, so mix these plants into the middle of perennial beds with other tall growing perennials to cover up the browning foliage. Grows well in most soil types including clay. This oriental poppy is an outstanding seed grown variety.
