About
Iris 'Alice Harding' is a clump-forming cultivar of the Iris genus, known for its deciduous foliage and upright stems bearing distinctive flowers with three broad fall petals and three smaller standard petals. This cultivar thrives in well-drained, fertile loam soil with a neutral pH, ideally in full sun and a sheltered position facing south, east, or west. Suitable for city gardens, patios, and flower borders, it flowers in spring and is hardy to UK zone H6. Propagation is by division of rhizomes, which should be planted shallowly with the tops exposed to avoid waterlogging.
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.
