Iris unguicularis 'Walter Butt'

Archive entry 06.11.22

The winter flowering Iris unguicularis forms are a delight in a sunny well drained location. The foliage can become distinctly ragged during winter, but it is easily overlooked when the flowers open.

'Walter Butt' has striking flowers in a soft lilac blue during the coldest part of winter. I was shivering when I took this photo, which is why it is out of focus.
