The blooms have red center flares on petals, and 'Bartzella' makes a lovely short cut flower. Roger Anderson of Wisconsin introduced Paeonia x 'Bartzella' in 1986, after years of hybridizing work. 2021 PHS Gold Medal Plant.
PRN Preferred: A heavy bloomer with bright yellow flowers. Since is it an Itoh, the foliage looks good all season long.
