The agave is certainly not a common garden plant, but you see the large plant more often now in sheltered places in gardens where there is room for them. The agave species with their sturdy blue leaves covered with large spines originate from Mexico and in our country they definitely need to be in full sun. In winter, shelter is needed. In a tub or large pot they are an ornament in the garden or on your terrace.
