    Plant Sizes

    Just wanted to give you a heads up that the image of the plant you'll be receiving is just an example of what you can expect. Each plant is unique and may vary in size and shape, so it won't be an exact match to the photo. If we provide a size guide, keep in mind that it's just an estimate and that plants can vary in size depending on the time of year.

    Our Delivery Promise to you

    If you choose Express Delivery, we will replace any plants that are damaged due to delays. Express Delivery is a fast, trackable, and reliable option with a one hour delivery window. It also ensures that the plants will arrive in the same condition as when they left our facility. If you choose a different postage option, such as Tracked 24 or Tracked 48, you will not be covered for any damages due to delays and will assume the risk yourself if the plants do not arrive in good condition. Express Delivery includes an insurance policy, which may cost more but provides added peace of mind.


If you order before 4pm we dispatch the same working day (Mon-Fri). Shipping prices start at £4.99 depending on the speed of delivery required.

    A fast growing plant with very fine needle-like leaves. As the plant grows so fast it competes with algae, so is an ideal plant for a starter aquarium and ponds. The plant should be pruned regularly to keep its form and encourage new growth.

    Note - this plant does not come with any weights and the picture is an example of what will be received. To anchor in your tank, push roughly 5cm down. It's also a true aquatic which means it only grows under water and as a result, snails may arrive on this plant.

    Delicate and different

    What a lovely plant, with its delicate feathery appearance! It has settled in well a week after delivery, and was today introduced to the fishes in the other tank! I haven't tried Hornwort before, but, like Elodea, it doesn't take up much room without a plant pot, so if it does well I may choose this again.

    I love this plant, I recieved a generous amount of cuttings for the price, they are all healthy and beginning to grow in my tank

    Unfortunately the plant took over a week to arrive which was down to delays with Royal Mail. I was expecting the plant to be pretty damaged but it was completely unsalvageable. It was packed in a sandwich bag with a bit of water and was broken up into tiny bits which were basically impossible to pin down in my tank. On top of this most of it had gone brown and died off. I would recommend if you’re thinking of buying to be mindful that Aqua Essentials don’t offer refunds or replacements if there are problems with Royal Mail delivery as i spent about £7 + £5 shipping for a plant which is completely unusable. I also had no reply to the emails I sent their customer service address.

    Love the plants, arrived very healthy. A bit tricky to keep it in the ground as they grow no roots, but I managed with some weights and it's swaying in the current.

    Your plants will be wrapped with recyclable Honey Comb wrap - sounds cool because it is :). It interlocks which means we don't need to use tape either, reducing our impact on the environment.

    Not only is delivery fast with DPD Express but it's also green as they offset all the carbon their vehicles produce. Guilt free delivery which we're very proud of...
