Tropica Potted Plants at www.aquaessentials.co.uk. If you want the best possible plants, then look no further. These aquarium plants are the greenest, healthiest, best rooted and most lushous plants in the world, grown by market leaders Tropica. We get excited when their plants arrive with us (on a weekly basis) and for good reason. It's always a pleasure unwrapping the box of neatly placed plants in their decorated cardboard box. Everyone likes top of the range don't they and these plants are no exception. You don't get any better and when you invest in Tropica plants, you'll see why.
