White flowers are loved for their versatility and ability to blend into any style of planting scheme, and this glorious Dutch iris ‘Alaska’ will certainly not disappoint in that department. Peaking between May and June, you’ll get the enjoyment of watching the delicate and elaborate crisp-white blooms unfurl right on the cusp of summer, just as earlier spring varieties are starting to fade. Entirely white, but with each fall showing off a gleaming yellow blotch, these sophisticated Irises provide a subtle hint of colour which just adds that lovely extra detail.
Whether you have a white border or the full colour spectrum in your garden, the shining white blooms of Dutch Iris ‘Alaska’ will fit right in without fuss. These hardy and resilient plants are also very easy to grow, rewarding very little effort with a floriferous display from late spring to early summer year after year. If you enjoy cutting flowers from the garden to make indoor arrangements, these are a must - Dutch Irises are loved by florists for their excellent vase life, long stems and showy flair of petals which add detail and luxury to both contemporary and traditional bouquets.

Plant calendar
Check whether your varieties prefer sun or shade, then choose a sheltered spot with well-drained soil. Most spring bulbs also grow well in containers.
Remove weeds and loosen compacted soil. Improve heavy ground with organic matter and horticultural grit. For containers, use peat-free multipurpose compost and ensure good drainage.
Plant at the depth recommended for each variety, as their requirements differ. Position shoots or pointed ends upwards. If the correct direction is unclear, plant them on their sides.
Follow the recommended spacing for each variety. Planting in clusters or informal drifts creates a natural display, but avoid placing them directly against one another.
Water after planting if the soil is dry. Keep containers lightly moist but never waterlogged. After flowering, allow foliage to yellow naturally before removing it.
