The Bowl planter is a wider version of the Tall Cylinder, available in 4 sizes up to 70cm diameter. It's fibreglass, so lightweight and frostproof and available in any RAL colour and a range of special finishes like stone or even rust.
The larger sizes will take quite large plants or even small trees. You might also want to look at the wide cylinder, also available in the fibreglass range.
