About
Iris 'Ajax the Less' is a herbaceous perennial cultivar within the Iris genus, known for its upright habit and blue-green foliage. This small bearded iris (SDB) thrives in full sun, ideally in a south-facing, sheltered position with well-drained, sandy, neutral soil that remains dry. It is hardy to UK zone H7 and typically flowers in spring. Suitable for border planting and as an architectural plant, it requires shallow planting of rhizomes and benefits from division or seed propagation.
About the genus
Iris takes its name from the Greek goddess of the rainbow, and for once the naming feels entirely earned. I can't think of another genus that covers so much ground — inky purples, burnt apricots, clean whites, blues that seem lit from inside — or so many situations. There are bearded irises that want their rhizomes baked in full sun, Siberian types happy in ordinary border soil, and species that will sit contentedly at the edge of a pond. What they share is the flower: three petals standing up, three falling away, built with a kind of architectural confidence most plants never attempt. Even out of bloom the foliage earns its place — those upright fans of blue-green leaves hold a border together for months. I grow them for the fortnight in May and June when nothing else in the garden can compete, and I've made my peace with that. Some plants are for the long haul. An iris is an event.
