What happens afterward matters just as much. The leaves are narrow, stiff, and strictly upright, more like an ornamental grass than an iris, and they hold that posture through summer heat and into fall while neighboring perennials sprawl. The seed pods that follow the flowers dry to a warm tan and are worth leaving standing into winter.\u003c\/p\u003e\n\n\u003cp\u003eThis is a plant that improves with age. Clumps thicken year over year and flower more heavily as they do, and they can sit undisturbed for ten years or longer before the center thins enough to justify dividing.\u003c\/p\u003e\n\n\u003ch2\u003eCare\u003c\/h2\u003e\n\n\u003ch3\u003e\u003cstrong\u003eCaesar's Brother Siberian Iris Care\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003ePlant Caesar's Brother Siberian Iris in full sun to partial sun in average to moist, fertile soil. Unlike bearded iris, the rhizomes are planted an inch or two below the surface rather than at soil level. It tolerates consistently damp ground and does well at a pond or rain garden edge, though it does not want to stand in water through winter.\u003c\/p\u003e\n\n\u003cp\u003eWater regularly through the first two seasons. Established clumps handle ordinary dry spells but flower best where moisture is steady through spring.\u003c\/p\u003e\n\n\u003cp\u003eA single spring application of \u003ca href=\"https:\/\/almanacplanting.com\/products\/slow-release-fertilizer\" target=\"_blank\" rel=\"noopener\"\u003eslow release fertilizer\u003c\/a\u003e is enough. Cut spent flower stems off at the base unless you want the seed pods for winter interest. Leave the foliage standing through fall and cut it back to a few inches in late winter. Divide only when bloom drops off and the clump has hollowed out in the middle.\u003c\/p\u003e\n\n\u003ch2\u003eSize\u003c\/h2\u003e\n\n\u003ch3\u003e\u003cstrong\u003eWhat Size is the Caesar's Brother Siberian Iris for Sale Online?\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eOur Caesar's Brother Siberian Iris ships in a greenhouse-grade grow pot and is appropriately sized for its container at the time of shipment.

Clumps thicken and widen gradually for a decade or more.\u003c\/p\u003e\n\n\u003ch2\u003eAdditional Information\u003c\/h2\u003e\n\n\u003ch3\u003e\u003cstrong\u003eHow is Siberian iris different from bearded iris?\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eSiberian iris has narrower, grassier foliage that stays upright all season, smaller and more delicate flowers, and no beard on the falls. More practically, it is planted below the soil surface rather than on top, and it is not susceptible to the iris borer and rhizome rot that plague bearded types.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eWill it grow in wet soil?\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eYes. It tolerates consistently moist ground better than most perennials and is a good choice for pond edges, rain gardens, and low spots that stay damp through spring. It will not survive standing water through winter.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eHow often does it need dividing?\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eRarely. Clumps can go ten years or more before the center thins and bloom falls off. When that happens, lift and split in late summer or early fall.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eIs it deer resistant?\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eYes. Deer and rabbits both leave iris foliage alone, which makes it a dependable choice in unfenced borders.
