Iris hybrid (Sino-Siberian)

Sino-Siberian iris hybrids


A large and remarkably diverse group of 200 to 300 species, varying in flower color and form, cultural needs, and blooming periods (although the majority flower in spring or early summer). Leaves are swordlike or grasslike. Flowers (fragrant, in many kinds) are showy and complex in structure.

Iris hybrid (Sino-Siberian)

Specialists may offer various Sino-Siberian species. Most feature drooping falls and erect to flaring standards. Predominantly yellow colors are found in I. forrestii and I. wilsonii; predominantly purple to violet flowers occur in I. chrysographes, I. clarkei, I. delavayi, and I. dykesii. These species and their hybrids perform best where the climate is moist and relatively mild. Give plants good, acid soil and regular moisture.
