Copper King

Copper King.  Bremer.  2016.  Advanced generation lutea hybrid.  Seedling #NB31.  Large semi-double yellow flowers overlaid in coral and pink, giving the flowers a copper coloration effect.  Small maroon flares at petal bases.  Petals are fluted, ruffled, and lightly notched.  Pink sheath, red filaments, and yellow stigmas.  Flowers are carried on sturdy stems, allowing them to face outward.  Copper King has superior foliage with medium deep lobes and sharp leaflet tips.  Good stem hardiness and fast growth.  Height is approximately 5′, and width may be more than 7′.   Fertile both ways, but seed is challenging.  One of the most noticed lutea hybrids in our gardens over the last 6 years.  Parentage:  (Autumn Harvest x Rosalind Elsie Franklin).  Award “Best in Show” at the 2026 American Peony Society’s 2025 Flower Show and Exhibition.  AGE: Field-grown, 3+ year old graft or division from larger plants – our choice of available plant material upon harvest.
