Description
Let the gleaming flowers of Iris 'Louise' light up your garden at the end of winter—it’s exciting little glimmers of early spring like this which lift the mood by surprising levels when they appear on those short, chilly days of February. Whether they shimmer in the late winter sun or sit there surrounded by snow, there’s something very clean and elegant about a display of fresh white blooms. For a dwarf plant, it’s remarkable how tough, determined and resilient they are. They were born to shine and shine they will, whatever the weather!
Braving the cold to pop up with a fantastic flurry of snowy white flowers in February, it’s a good job that Iris reticulata 'Louise' is hardy to at least -20C and will simply laugh in the face of freezing temperatures. What’s more, you can look forward to these perennial bulbs reappearing for a repeat show every year. Being a small plant, it’s great for small places. But give these white dwarf irises a spot where they’re easy to see and admire—window boxes, pots or raised planters give them some extra height. On the other hand, Iris 'Louise' will look natural and glorious in a gravel garden, border or rockery area.
