  • Description

  • Notes

'Ceasar's Brother' is a siberian iris selection with deep blue flowers on stalks that rise to about 36 inches. Flowers bloom in late spring, and are followed by interesting seed pods. Foliage is narrow, erect, and and a rich green, turning orange to brown in the fall. Not for a low-water garden, but certainly worth including in perennial borders that receive weekly watering.
Grow in full sun to part shade in well drained soil. Though it is not particular about soil type, it will grow best in a fertile, loamy soil. The flowers are lovely cut, but the seed heads are quite ornamental and its worth letting some go to seed. The foliage is very persistent into the winter months and provides a pleasant winter presence; cut back in late winter to early spring as new growth emerges.
