Paeonia ostii, or Osti’s tree peony, is a spectacular specimen from China, known for its striking blooms and elegant leaves. This endangered species, named after Italian peony expert Dr. Gian Lupo Osti, is cultivated in several Chinese provinces despite its native home being the Henan province's forested slopes. Characterized by large 2-pinnate leaves and lovely white fragrant flowers with dark red blotch and yellow stamens, it grows 3-5’ tall and broad, creating an impressive display in any garden. Paeonia ostii is not just a visual delight; it's also used in traditional medicine in China. Its hardy stems stay strong during winter, requiring minimal pruning, and these long-lived plants serve as stunning accents, either alone or as a backdrop for other flowering plants. Best propagated in fertile, neutral to slightly alkaline soils, they are tolerant of summer heat. Please note, these plants thrive in cold winter temperatures, making them unsuitable for mild or warm winter climates.
