Itoh Peony 'Scrumdiddlyumptious' (Paeonia × itoh 'Scrumdiddlyumptious') gives you lush, peony-style blooms with a creamy yellow base and soft pink tones. As an intersectional (Itoh) peony, it combines strong stems and a full, rounded habit with excellent garden presence.
Plant it where you can enjoy the flowers up close and give it room to mature. Expect a height of about 24-36 inches with a similar 24-36 inch spread, creating a substantial clump that looks great among other perennials and shrubs.
For best performance, grow it in full sun to part shade. In cooler climates, more sun typically supports the best flowering; in hotter areas, a bit of afternoon shade can help the foliage stay fresh. Choose fertile, well-drained soil, and water regularly during establishment, then water during extended dry periods.
Peonies dislike frequent disturbance, so pick a long-term spot. Keep mulch pulled back from the crown, and avoid planting too deep. After frost, cut herbaceous stems back near the ground and clean up spent foliage to keep the planting tidy for next year.
Hardy in USDA Zones 4-8, this Itoh peony is a reliable spring-to-early-summer highlight that returns for years with minimal fuss once settled in.
