With YOUR TREE lowering the emission of carbon dioxide becomes an educational task for both young and old. Trees have the unique quality of contributing positively to the climate as they absorb carbon dioxide from the air as they grow. YOUR TREE planting pot comes in four different colours and with two kinds of seeds, so they can be put together for all kinds of creative patterns while growing on the windowsill. After approx. 1 year YOUR TREE can be planted out and with time, it can grow up to 20 to 30 metres tall. Great educational gift idea. The blue pot comes with pine seeds.
