Growing from bulbs, the group contains 10 species, including Iris histrio and Iris danfordiae, which usually only flowers well once before fading away. Amongst those 10 reticulata irises is Iris reticulata, too. Though these species are all slightly different, they all need the same growing conditions and we can treat them as different varieties of the same thing. Reticulate means ‘netted ’ and refers to the pattern on the bulbs’ dry skin.
These are superb little winter and early spring plants for small pots, window boxes, raised beds and rock gardens, or other sunny and free-draining situations. You can buy them in flower in winter and spring to spark up dull corners, or plant bulbs in the autumn.

- Grow in sunny, well-drained containers or beds (though they look great in containers, they may not flower so well again in their second year)
- All are hardy as long as they’re not waterlogged
- Plant bulbs in autumn. Plant deeper than you’d expect, at 10-15cm, to help them flower next year
- Feed with liquid tomato feed every two weeks from when the flowers fade
