Long Window Sill Planters Of course these planters don't have to sit on a window sill, but there is something about their form which suggests that they could fit that bill perfectly. The planters are made from a lightweight metal which has been coloured to take on a rusty hue. There is a narrow rim to each piece. Beneath the rust colouring you can just see the galvanized metal. The construction of the planters is not suce that they are meant to hold water, there are small gaps in the corner where the folded metal meets but equally you may want to add a layer of gravel into the base of the planter to aid drainage if you plan to plant directly into them. They would look great housing sempervivum or alpine plants such as auricula or lewisiana. You could also use them to grow leafy herbs - sowing the seed directly into compost in the planter. Measurements: The smaller planter measures 25.1cm x 8.9cm x 8cm The larger planter measures 34.5cm x 9.5cm x 8cm
