|The so-called Tree Peony is really a deciduous shrub, with flowers up to 1 foot across. Single, semi-double, and double, silky-petaled blooms are white, pink, lavender, purple, yellow, and bicolor. Bloom best in cold climates, but need less winter chill than Herbaceous Peonies. Choose the planting location carefully since they live a long time and dislike begin moved. Hardy in cold, they prefer full sun or partial sun in Zones 8 and 9. Plant grafted peonies 6 to 12 inches above the bud union. Choose seedlings in bloom to be sure what you are getting. Sold bareroot in winter or in containers year-round.
Some white varieties to look for are 'Savage Splendor' (single-flowering, with pink edges), 'Godaishu' (semi-double), and 'Tama Sudare' (double).
