Siberian iris

Iris 'Sparkle'

The Siberian Iris, also known by its botanical name Iris 'Sparkle', is a beautiful, low-maintenance perennial plant native to Siberia. It has bold, vibrant flower spikes that most commonly bloom in shades of deep, sky-blue but can also be found in purple, white, and pink. The foliage is grass-like, and its blade-shaped leaves are a shiny green colour. Though its flowers are small, each bloom offers a sparkling, eye-catching contrast to its environment. Hardy and easy to grow, these fast-spreading plants make a great addition to any garden.

watering

Siberian iris (Iris 'Sparkle') should be watered deeply once a week. This should be done early in the morning, so as to give the plant time to absorb the moisture before the heat of the day. During periods of drought, the plant may need to be watered twice a week; however, make sure the soil is still slightly moist before watering again. In the hot summer months, the plant may need to be watered 3 times a week. It is important not to over water Siberian iris as this can lead to root rot.

sunlight

Siberian iris (Iris 'Sparkle') needs full sun for best flowering and growth. Urban locations with polluted air can require more shade, however. It should be planted in a location that receives at least 6 hours of direct sunlight a day. In ideal conditions, it will flourish in 8-10 hours of direct sun daily, but it can manage with as little as 4 hours on some days. Morning sun and late afternoon shade is ideal to prevent scorching of the foliage.

pruning

Siberian iris (Iris 'Sparkle') should be pruned once a year in late autumn or early spring when the leaves turn brown. Pruning helps to keep the plant tidy and to encourage more flowering. One should begin by deadheading and cutting away any flowers that have finished blooming. This helps to keep the plant neat and to promote more blooms in the future. Cut back the foliage to 12 to 15 inches tall, removing any old, hollow, or dead leaves. Finally, prune away any stems that are damaged or misshapen. Taking care not to damage healthy stems and leaves, and using sharpened pruning shears, is key when pruning Siberian iris.
