This pond plant is semi-evergreen, so it can lose some of its foliage in winter. In colder regions or more exposed gardens, it may lose it all, but then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Depth of water: 5-25cm (2-10in)
  • Soil: reliably moist or boggy soil
  • Rate of growth: fast-growing
  • Flowering period: July and August
  • Hardiness: fully hardy

    Sulphur yellow flowers, often with brown markings appear from midsummer amongst the upright grey-green leaves. This native, yellow flag iris was once commonly found on marshy land and riversides and is ideal for planting at the margins of a large lake or pool. It also flourishes in deep, reliably moist soil that has been enriched with well-rotted organic matter.

  • Garden care: These plants are potted up (using a suitable aquatic compost) into 1-litre aquatic pots. These pots are made of a fine mesh, which allows water to circulate through the compost, providing the plants with both oxygen and nutrients. If you are using them as a aquatic plant, they can be placed straight into the pond, however they will preform better if planted out sooner rather than later. To enhance flowering divide congested clumps every three to five years.
