Polystone is a frost proof material and extremely durable. Each planter is made from a mix of special unsaturated resin, MMA and natural minerals and suitable for indoor and outdoor use. There are 5 contemporary planters in the Polystone range to choose from and they are available in either black or white. The Polystone Cubed Planter is perfect for housing specimen trees such as Bays, Ligustrum, Photinia and Olives. The extra large Polystone Jumbo Trough and Jumbo Pot each have a massive planting capacity. Despite their size and wide walls they are contemporary in appearance with well crafted round edges and perfect for filling any void areas on the garden patio. There are two tall garden planters in the Polystone range. The extra large High Square Planter stands 90cm high and the extra large Pillar is one meter tall. Both planters are perfect for planting up with topiary balls (buxus sempervirens) and will majestically display each specimen.
