Donau' is a tender to half-hardy, clump-forming, perennial with broad, arching, strap-shaped, glossy, dark green leaves and sturdy, erect stems bearing large, rounded heads of trumpet-shaped, pale-blue flowers with a dark-blue central stripes, from late spring into midsummer.
Thrives in full sun in fertile, moist and well-drained soil. In a hot climate area, Agapanthus will do better in partial shade. Do not allow plants to dry out except when dormant. Bear in mind that most varieties will lean toward the sun, which makes a south facing border the best location.
