What Makes it Special?

Landscape Attributes
Caesar’s Brother Siberian Iris is an herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. Deer don’t particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Planting & Growing
Caesar’s Brother Siberian Iris will grow to be about 28 inches tall at maturity extending to 4 feet tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. The flower stalks can be weak and so it may require staking in exposed sites or excessively rich soils. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant does best in full sun to partial shade. It is quite adaptable, prefering to grow in average to wet conditions, and will even tolerate some standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.



Want more info on sizes?
IndyPlants sells landscape size plant material. These often come in black nursery containers and are classified in sizes such as #2, #3, #5, etc. This correlates to the volume of the container, 2 gallon, 3, gallon, 5 gallon, etc. The bigger the number, the larger the pot, and the larger the plant. You’ll also see larger sizes such as 2” BB, 2.5” BB, 3” BB, etc. This stands for ‘Balled & Burlapped’. These plants are usually much larger and are not transported in black nursery pots. The sizing correlates to the diameter of the trunk of the tree.
