There is a conservatory attached to the house here. Actually, conservatory is a rather grand name for it: it is more like a lean-to shed with glass walls. Its best feature is a bottomless planter in its sunny south-west corner. The soil in the planter is contiguous with the earth beneath and so there is little need for watering: the moisture wicks up from the ground.
In it is a Jasmine plant that grows very successfully there. At the moment it is in full bloom and its perfume pervades the house.
