Iris cristata ‘Alba’
Blooming Time
Exposure
White flowered crested iris is just as charming as the parent species but with snow-white flowers during spring. A native cultivar (nativar), ‘Alba’ blooms brightly for a few weeks and then gives way to lovely blue-green sword shaped foliage. Its rate of spread is moderate, and in time it can form mats that are two-feet in diameter or larger. White flowered crested iris is excellent as a small to moderate scale ground cover and can be inter-planted with bulbs of contrasting flower color as well as other forms of crested iris (of contrasting flower color).

Care
Watering:
White Flowered Dwarf Crested Iris is moderately drought tolerant but benefits from occasional watering, to maintain soil in a moist but not wet condition, during the summer months.
Fertilizing:
White Flowered Dwarf Crested Iris is a moderate feeder, benefiting from a couple of annual applications of slow release fertilizer. A spring application of a 3-1-2 ratio (such as a 15-5-10) can be applied at a rate of about 10 pounds per 1000 square feet, and during early fall, an application of a 2-1-2 ratio (such as a 10-5-10) can be applied to encourage root development and cold hardiness.
Pruning:
White Flowered Dwarf Crested Iris is a deciduous plant (nonevergreen) and does not require pruning. It is perfectly acceptable to allow the dropped leaves to decompose and nourish the soil.
