Starwort | Callitriche stagnalis (5 Weighted Bunches)

Description

Starwort (Callitriche stagnalis) is a vigorous, fully submerged oxygenating plant ideal for keeping garden ponds clear and healthy. This fast-growing green oxygenator remains active into autumn and winter, helping to maintain good water quality outside the main summer season.

In fast-flowing water, Starwort’s fine leaves stay below the surface, while in still, shallow areas they may rise just a centimetre or two above the water. It thrives in full sun to part shade, making it a versatile choice for a wide range of pond positions.

As an underwater oxygenating plant, Callitriche stagnalis provides valuable cover and habitat within the water, supporting a more balanced pond ecosystem. Its dense growth offers shelter for aquatic life and contributes to a more natural look in wildlife-friendly ponds.

For help choosing the right types and quantities of oxygenating pond plants for your pond, see our Oxygenating Pond Plants Guide.

    Care Instructions

    Starwort (Callitriche stagnalis) Care Instructions:

    Starwort is a fast-growing oxygenating plant that thrives in both full sun and part shade, making it ideal for a variety of pond environments. For best results, you can either drop a weighted bunch directly into your pond or plant it in soil to encourage stronger growth. This versatile plant contributes to a healthy aquatic ecosystem by oxygenating the water and providing shelter for aquatic wildlife. Starwort is particularly effective during autumn and winter when other plants are less active. Its dense green foliage enhances water clarity and supports pond life year-round. Whether used in shallow waters or slow-moving streams, Starwort helps keep your pond vibrant and oxygen-rich with minimal effort.

    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.
