About
Iris 'Anniversary Celebration' is a clump-forming cultivar of the Iris genus, which includes rhizomatous perennials with slender leaves and upright stems bearing distinctive flowers. This deciduous plant thrives in full sun and prefers well-drained, neutral loam soil in sheltered positions such as south, east, or west-facing aspects. It is hardy to UK zone H6 and is suitable for city and courtyard gardens, cottage and informal gardens, patios, containers, flower borders, and as cut flowers. Flowering occurs in spring, with rhizomes planted shallowly to avoid waterlogging and propagated by division.
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.
