Iris louisiana 'Black Gamecock'

    Description

    Iris louisiana 'Black Gamecock' is a striking marginal pond plant, prized for its giant, deep purple, almost black blooms. Flowering in June and July, this Louisiana iris brings dramatic colour to the water’s edge and looks equally at home in wildlife ponds, formal pools, or boggy borders.

    This hardy marginal thrives in full sun to part shade and enjoys consistently moist conditions, making it ideal for planting in shallow water or damp soil around the pond. With a medium growth rate, Iris louisiana 'Black Gamecock' forms attractive clumps that add structure and height to the pond margin.

    Like other marginal plants, it helps create valuable cover and shelter around the pond edge, supporting a more natural, wildlife-friendly environment. Please note: as with all irises, the tubers are harmful if eaten and should not be consumed.

      Care Instructions for Iris louisiana 'Black Gamecock'

      Plant this marginal iris in full sun to part shade to ensure healthy growth and vibrant blooms. Its medium growth rate makes it ideal for pond edges and moist garden areas. After the foliage dies back in autumn, trim the plant carefully to just above the water surface to promote new growth. If you delay trimming until spring, take extra care to avoid damaging emerging shoots. This routine helps maintain the plant's health and keeps your water feature tidy. Remember, 'Black Gamecock' prefers consistently moist conditions and contributes a stunning deep purple color to your garden from June through July.

      Ordering, Shipping, Tracking and Returns
      Ordering & delivery


      Some products are ready for immediate dispatch, while others are sold for a later delivery period so that they can reach you in good condition and at the right point in the growing season.

      The expected delivery period for the product or variant you choose will be shown below the Add to basket button and again in the basket and checkout.

      30 litre plants and some larger items are sent by specialist pallet delivery rather than standard parcel.

      If your order contains products with different delivery timings, it may be split into more than one shipment. Plants or products that are ready for immediate dispatch will normally be sent first, while later-season plants will be sent when they are ready. This helps us send live plants at the appropriate point in the season and in suitable condition to travel.

      For full details, please see our Shipping Policy.

      Returns & problems on arrival

      Because we sell live aquatic plants and molluscs, some parts of our policy work differently from standard retail.

      Live plants and molluscs are perishable and are not suitable for routine returns once they have been prepared for dispatch.

      If there is a genuine issue on arrival, please contact us within 24 hours using the form on our Contact page, with your order number, photographs, and a short explanation.

      We will always review genuine issues carefully and fairly. Depending on the circumstances, the appropriate remedy may include a replacement, refund, or partial refund where appropriate.

      Please do not send anything back unless we have agreed this with you in writing first.

      For full details, please see our Refunds & Returns Policy.
