Bearded Iris 'Clarence'
Heavenly violet-blue blooms with sweet fragrance.
Blooms early summer
This U.S.-grown, re-blooming bearded iris puts on a spectacular show of vibrant denim-blue-violet flowers with bluish white standards.
‘Clarence’ is floriferous, producing abundant, blousy blooms (up to 6 per stem!) in early summer and, if happy and well-cared for, a second flowering in early fall. Known to be one of the most dependable re-blooming varieties; see our growing instructions for more info on how to encourage early fall blooms.
Grows to 35” tall and prefers full to partial sun.
Does not ship internationally.

Bearded Iris should be planted in full sun to partial shade - they require at least 6 hours of sunlight per day. They perform best in well-drained soil and should be planted on the surface of the soil with any roots facing down and buried, with the fan of the leaves and the upper surface of the rhizome facing up and exposed. Provide a layer of light mulch (such as straw or leaves) the first winter, but remove this as soon as the weather warms in spring; beyond this do not mulch.
Water in after transplanting; beyond that only provide water if it is extremely dry. Plants benefit from a low nitrogen fertilizer in early spring and just after blooming to nourish the rhizomes. Apply fertilizer around the rhizomes, but not directly onto them.
Remove spent flowerheads after blooming is finished, and prune back the foliage to about 6" in fall after several frosts have occurred.
Bearded Iris like a lot of airflow and don't do well when crowded, so as your clumps grow they should be divided every 3-4 years to maintain 16" spacing.
To encourage a second fall bloom period in re-blooming varieties, make sure to be diligent about cutting back spent flower spikes and providing low-nitrogen fertilizer after the first flowering period has finished.
